Answer:
x + 20° = 35.56°
3x + 10° = 56.68°
5x + 10° = 87.8°
Step-by-step explanation:
Assume;
Given measures are angle of a triangle
x + 20°
3x + 10°
5x + 10°
Find:
Value of each angle
Computation:
We know that, sum of all interior angle in a triangle is 180°
So,
We say that
x + 20° + 3x + 10° + 5x + 10° = 180°
9x + 40° = 180°
9x = 140°
x = 15.56°
So,
x + 20° = 15.56 + 20 = 35.56°
3x + 10° = 3(15.56) + 10 = 56.68°
5x + 10° = 5(15.56) + 10 = 87.8°
