Answer:
the top angle is 48
the bottom right angle is 42
Step-by-step explanation:
The sum of the angles of a triangle is 180
90 + 8x+7x = 180
Combine like terms
90 +15x = 180
Subtract 90 from each side
15x = 180-90
15x = 90
Divide by 15
15x/15 =90/15
x = 6
8x = 8*6 = 48 so the top angle is 48
7x = 7*6 = 42 so the bottom angle is 42
Solution given:
8x°+7x°+90°=180°[sum of interior angle of a triangle is 180°]
15x=180°-90°
x=90/15
x=6°

Answer:
32, 36, 40
Step-by-step explanation:
8x + 9x + 10x = 108
27x = 108
x = 4
4 × 8 = 32 - 1st side
4 × 9 = 36 - 2nd side
4 × 10 = 40 - 3rd side
