Question

please give me answer of 8

Answer 1

two acute angles=90
x+x/2=90
3x=90
x=30
The two acute angles are 30 and 60 degrees

Answer 2

make a triangle with angles a, b, c right angled at b
angle a+b+c=180
a + 90 +2a = 180
3a = 90
a = 30
so the smaller angle will be be 30 and bigger will be 60
30 + 90 + 30 = 180

hope this helpss..
