Answer:
Step-by-step explanation:
in a triangle, the angles add up to 180
therefore:-
90+ x+ 2x = 180
90+3x=180
3x=90
x=90/3
x=30
2x=60
these are the two angles

Step-by-step explanation:
90 + x + x = 180 ( sum of int. angles of triangle is 180°)
90 + 2x = 180
x = 180-90/2
x = 90/2
x = 45
2x = 2×45
= 90
