Answer:

No

Congruent tests: Side-Side-Side, Side-Angle-Side, Angle-Side-Angle, Angle-Angle-Side, Right angle-Hypothenuse-Side any 1 tests must be the same for both triangles

in this case, only the 3 angles are the same, which is a similarity test, not a congruence test

this is a topic on similarity and congruency. If you wish to explore more into this topic you can give me a follow on Instagram (learntionary) I'll be posting the notes for this topic soon and will also be posting other topics' notes and some tips :)

Congruent triangles are similar triangles.

There is no enough information to prove that the triangles are congruent

For triangles to be congruent, then the corresponding sides and angles must be congruent.

From the attached figure, only the angles of the triangles are guaranteed to be congruent.

There is no information about the sides of the triangles.

Hence, there is no enough information to prove that the triangles are congruent

Answer:

Step-by-step explanation:

Law of cosines

In a general triangle, the law of cosines relates the lengths of the sides of the triangle to the cosine of one of its angles.

The law of cosine is expressed as:

[tex]\displaystyle c^{2}=a^{2}+b^{2}-2ab\cos x[/tex]

Where a and b are the lengths of two sides of the triangle, x is the angle contained between them, and c is the other side length.

If all side lengths are known, we can solve the above equation for the angle x:

[tex]\displaystyle x =\arccos \left({\frac {a^{2}+b^{2}-c^{2}}{2ab}}\right)[/tex]

From the image, we must select a and b as the sides adjacent to angle x in any order. Thus a=17, b=22, c=24. Substituting:

[tex]\displaystyle x=\arccos \left({\frac {17^{2}+22^{2}-24^{2}}{2(17)(22)}}\right)[/tex]

Operating:

[tex]\displaystyle x=\arccos \left({\frac {289+484-576}{748}}\right)[/tex]

[tex]\displaystyle x=\arccos \left({\frac {197}{748}}\right)[/tex]

Using a scientific calculator:

Answer:

The answer is A. y=2x+4

Step-by-step explanation:

The y-intercept is on positive 4, so the equation will end with +4. the rise over the run is 2/1, which is simplified to 2. So 2x. So the answer is y=2x+4.

A = 256cm square

Step-by-step explanation:

(a) No

[tex]f(x) = 12 - 5x[/tex]

[tex]f(0) = 12 - 5(0)[/tex]

[tex]f(x) = 12 - 0[/tex]

[tex]f(x) = 12[/tex]

Hence,

f(0) is unequal to 0.

(b)

[tex]f(x) = 12 - 5x[/tex]

[tex]f( - 1) = 12 - 5( - 1)[/tex]

[tex]f( - 1) = 12 + 5[/tex]

[tex]f( - 1) = 17[/tex]

(c)

[tex]f(x) = 12 - 5x[/tex]

[tex]f(x) = 6[/tex]

[tex]6 = 12 - 5x[/tex]

[tex]6 - 12 = - 5x[/tex]

[tex] - 6 = - 5x[/tex]

[tex]6 = 5x[/tex]

Answer:

Steps:

1. locate the incenter by constructing the angle bisectors of at least two angles of the triangle.

2. construct a perpendicular from the incenter to one side of the triangle to locate the exact radius.

3. place compass point at the incenter and measure from the center to the point where the perpendicular crosses the side of the triangle (the radius of the circle).

4. draw the circle.

Constructed incenter '[tex]I_{c}[/tex] 'of the the inscribed circle after bisecting ∠P, ∠Q , ∠R and draw the tangents from incentre to one of the side of the triangle.

Answer:

54

Step-by-step explanation:

What the shorthand is telling you is wherever you see an x on the right, you put in -8

f(x) = 6(1- x)

f(-8) = 6(1 - - 8)

f(-8) = 6(1+8)
