A. 86
B. 65
C. 130
D. 58
find the value of c

b) 65°

Step-by-step explanation:

triangles always equal 180°

from the given information, these two triangles appear to be congruent. therefore, the angle that is 29° in the left triangle should apply to the triangle on the right.

so 29° + 86° = 155

180 - 155 = 65

the missing angle is 65°

hope this helps :)

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
