Question

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

Answer 1

Answer: 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 :)
