Question

In triangle FGH, the measure of angle F is 42 degrees and an exterior angle at vertex H has a measure of 104 degrees. What is the measure of angle G?

Answer 1

given that m<a=74 and m<b=52, find the measures of angles x and y

Answer 2

76

Answer 3

The measure of exterior angle is equal to sum of two interior angles. one interior angle is given i.e 42 degree. let's suppose the other unknown angle is x. Let's do the calculation now:

x+42=104
104-42=x
x= 62 degree

62 degree is the answer. Glad I could help :)
