Answer:
∠A = 45° ; ∠B = 63° ; ∠C = 72°
Step-by-step explanation:
A:B:C =5:7:8
let the angles are 5x,7x and 8x.
In a triangle the sum of the angles = 180.
∴5x+7x+8x =180
⇒20x = 180
x =9°
∴∠A = 45° ; ∠B = 63° ; ∠C = 72°

Step-by-step explanation:
Lets take the angles as 5x,7x and 8x(their ratio is 5:7:8)
Since all the angles of a triangle add up to 180°
,5x+7x+8x=180°
20x=180°
x=180/20=9°
first angle=5x=5×9=45°
second angle=7x=7×9=63°
third angle=8x=8×9=72°
Hope it helps
