Pls answer this question and I want the answer with full explanation....​

Answer 1

Answer:

160 degree is the answer for your question

Step-by-step explanation:

Let interior angle be x

Exterior angle = 1/4x + 5

So :

x + 1/4x + 5 = 180

5/4x + 5 = 180

5/4x = 180 - 5 = 175

x = 175 ÷ 5/4

x = 175 × 4/5

x = 35 × 4

x = 140

So interior angle is 140 degree

Exterior angle is 1/4 + 5 of 140 = 40 degree

Now we should should find 8/7 of interior angle ( 140 )

= 8/7 × 140 = 160 degree is the answer

$\huge\colorbox{magenta}{Àηѕωєя࿐ ❤}$

Let interior angle be x

Exterior angle = 1/4x + 5

A/Q,

x + 1/4x + 5 = 180

5/4x + 5 = 180

5/4x = 180 - 5 = 175

x = 175 ÷ 5/4

x = 175 × 4/5

x = 35 × 4

x = 140

So interior angle is 140° .

Exterior angle is 1/4 + 5 of 140 = 40° .

Now we should should find 8/7 of interior angle ( 140 )

= 8/7 × 140 = 160° ans.
