We know that, Two angles are said to be complementary, if the sum of their measures is 90°.
According to the Question,
⇒ ∠ABD + ∠DBC = 90°
⇒ (2x + 30)° + (3x + 20)° = 90°
⇒ 2x + 30° + 3x + 20° = 90°
⇒ 5x + 50° = 90°
⇒ 5x = 90° - 50°
⇒ 5x = 40°
⇒ x = 40°/5
⇒ x = 8
So, the measure of each angle will be,
⇒ ∠ABD = (2x + 30)°
= 2 × 8 + 30°
= 16 + 30°
= 46°
⇒ ∠DBC = (3x + 20)°
= 3 × 8 + 30°
= 24 + 30°
= 54° ▄▄▄▄▄▄▄▄▄▄▄▄▄▄Related Questions

Determine if XOY AND WOV are a linear pair, vertical angles or neither.
Geometry 9th!!
Answers
Answer:
It's neither
Step-by-step explanation:
it's neither because it can out be linear pair as in linear pair the sum of angles will be 180
65 + 60 = 125
it can out be vertical angles as vertical angles are of equal length
XOY and WOV are neither a linear pair nor a vertical angles.
What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
XOY and WOV Are given that are 60 and 65 degree respectively
For two angle become a linear pair there sum needs to be 180 degree
Since XOY + WOV = 60 + 65 = 125
Thus, these are not linear pair
For two angles to be vertical angles they were need to be equals
Since, XOY and WOV are not equal.
therefore, These two angles are neither a vertical angles nor a linear pair.

What is the greatest common factor of 48, 112, and 80
Answers
9514 1404 393
Answer:
16
Step-by-step explanation:
48 = 16·3
112 = 16·7
80 = 16·5
3, 5, 7 have no common factors. The GCF of {48, 112, 80} is 16.
_____
It can be helpful to recognize 48 = 16·3 and 80 = 16·5. A simple check shows 112 = 16·7, so 16 is the GCF.
__
You can find GCF(48,112) using Euclid's algorithm:
112 mod 48 = 16
48 mod 16 = 0 ⇒ GCF(48, 112) = 16
and the GCF(16, 80) is ...
80 mod 16 = 0 ⇒ GCF(16, 80) = 16
So, GCF(48, 80, 112) is 16.

What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
w = x/(a - b)
To solve the above expression in terms of w, a, and b make the subject as x.
Subtract by km on both sides:
w = x/(a - b)
On cross multiplication:
w(a - b) = x
As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

On a coordinate grid, has endpoints A(4, – 2) and B(x, y). The midpoint of is (– 3, 1). What is the x-coordinate of point B?
Answers
Answer:-10
Step-by-step explanation:
Formula for mid point is :
Mid point = ( (x1+x2)÷2 , (y1+y2)÷2) )
So, X1 = 4
X2 = X
Y1 = -2
Y2 = y
Now, use the formula
(-3,1) = ( (4 + x)÷2 , (-2+y)÷2) )
Now divide the sides for yourself to solve for midpoint for X and y separately
-3 = (4+x) ÷ 2 and 1 = (-2+y) ÷ 2
This is because 3 is the x coordinate of the mid point of A and B , so we equate it to (4+x) ÷ 2 because this expression basically gives us the x coordinate of mid point of A and B. So we already have the x coordinate of midpoint which is -3 so we can use this to find X coordinate of point B
So then we solve it by multiplying the 2 with -3 which gives -6
-6 = 4+X
Shift 4 on the other side and it will become negative 4
-6-4 = X
X = -10
Answer:
B (-10,4)
Step-by-step explanation:
Given A (4,-2) and midpoint M (-3,1) we can find equation of the line
y = mx +b
slope m = raise / run
m = (y1 - y2) / (x1 - x2)
m = (-2 - 1) / (4 - -3)
m = -3 / 7 = -3/7
given the midpoint M, then point B (x,y) must have the same length and slope as AM. So point B must have twice the rise and twice the run.
Slope was -3/7 so segment AB must be 2(slope) = -6/14, so from point A, point B will be from A (4,-2)
raise = y1 - y2 = -6
-2 - y2 = -6
-y2 = -6 + 2
y2 = 4
run = x1 - x2 = 14 = 4 - x2
14 - 4 = -x2
x2 = -10

subtract 17 from 153
8x = 136
divide 136 by 8

spend, and the T-shirts sell for $7 and $10. Write and solve an inequality that represents
the possible number of $10 T-shirts you can purchase. What is the minimum number of

Answers
Answer:
the minimum number of $7 T-shirts that you can purchase is 4.
Step-by-step explanation:
Let x number of T-shirts purchased at the price of $7.
and y number of T-shirts purchased at the price of $10.
According to the given condition, the total amount for purchasing the T-shirt is $48.
Therefore,
[tex]7x+10y\leq 48[/tex]
Also, you are planned to buy a total of six T-shirts.
[tex]x+y=6[/tex]
Solve, the above equation for [tex]y[/tex].
[tex]y=x-6[/tex]
Substitute the value of [tex]y[/tex] in the inequality.
[tex]\begin{aligned}7x+10(6-x)&\leq 48\\7x+60-10x&\leq 48\\-3x&\leq -12\\x&\geq 4\end{aligned}[/tex]

and to follow naming standards we now simply switch x and y, so that the inverse function is indeed again a function of x
y = -4/3 × (x + 1/3) = -4x/3 - 4/9
