Question

What is the value of x?

Answer 1

x = 8

Explanation:

Now we have to,

→ Find the required value of x.

We know that,

→ Sum of all angles in a triangle is 180°.

Forming the equation,

→ 4x + 103° + (5x + 5)° = 180°

Then the value of x will be,

→ 4x + 103° + (5x + 5)° = 180°

→ (4x + 5x) + (103° + 5°) = 180°

→ 9x + 108° = 180°

→ 9x = 180° - 108°

→ 9x = 72

→ x = 72/9

→ [ x = 8 ]

Hence, the value of x is 8.

Answer 2

x = 8

Explanation:

• What is the value of x?

the sum of the interior angles in a triangle is 180°, so we solve withy an equation

4x + 5x + 5 + 103 = 180°

9x = 180 - 5 - 103

9x = 72

x = 72 : 9

x = 8

----------------------------------

check

4 x 8 + 5 x 8 + 5 + 103 = 180 (remember PEMDAS)

32 + 40 + 5 + 103 = 180

the answer is good
