Question

I am bad at angles. can someone please help?

Answer 1

x=25

Explanation:

a triangles angles total to 180

we know we have one right angle, thats 90 degrees taken

90 degrees r now left

we combine the x'es, so now we have 3x+15

after subtracting 15 from 90, we have 75

so now our equation is 3x=75

75÷3=25

x=25
