ANSWER THE QUESTION IN EXPLAINATION AND ANSWER FAST PLS .
if the angles (4x + 4)° and (6x – 4)° are the supplementary angles, find the value of x. [2]​

Answer 1

Answer:

18 degrees

Step-by-step explanation:

Supplementary angles mean that when we add them up, their sum is 180 degrees.

Given: (4x + 4) + (6x - 4) = 180

4x + 4 + 6x - 4 = 180

4x + 6x = 180 - 4 + 4

10x = 180

x = 18

∴ Here, x is equal to 18 degrees.

Answer 2

Answer :-

• The value of x is 18.

To find :-

• The value of x.

Step-by-step explanation :-

• Here, it is given that (4x + 4)° and (6x - 4)° are supplementary angles. We have to find the value of x!

We know that :-

$\bigstar \: \underline{\boxed{\sf Supplementary \: angles \: add \: up \: to \: 180^{\circ}}}$

Therefore :-

$\longrightarrow (4x + 4) + (6x - 4) = 180$

$\longrightarrow4x + 4 + 6x - 4 = 180$

$\longrightarrow4x + 6x = 180$

$\longrightarrow 10x = 180$

$\longrightarrow x = \dfrac{180}{10}$

$\longrightarrow x = 18$

Hence :-

• The value of x is 18.
