Solve a triangle with a=32, b=38, and c=46.

Step-by-step explanation:

we have a triangle with

 a=32, b=38, and c=46

We can use the cosine rule to find the angles

It is

so plugging all the values we get

A= 43.5

Now for angle B , the formula is

plugging all the vaues again we get

B= 54.8

Now since for a triangle A+B+C =180

so C = 180 - 43.5- 54.8

C=81.7

option a

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

d. all of the above
