Answer:
75 degrees
Step-by-step explanation:
60 = 45= 75 = 180
Because every triangle has 180 degrees in it
Alright here we go
First we need to find the upper angle by doing 180 - 143 = 37. Because it’s a straight line.
Second we need to find angle ADC
a triangle has 180 degrees, and we have 38 and 37.
180 - (38+37) = 105
then we find what the question wants:
180 - 105 = 75 degrees
