Question

Find the measurement of each marked angle

Answer 1

where are the answers?

Answer 2

see below

Explanation:

The interior angle of the triangle on the right is 180 - ( 9x+12)

this plus the other two sum to 180 degrees

180 - (9x+12) + 4x-3 + 6x + 3 = 180

x = 12

then the angles are 6(12) + 3 = 75 4(12) -3 = 45 and 60°
