Question

Calculate the value X + 203x + 105x +10°​

Answer 1

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°
