Question

help me please i really need help

Answer 1

Answer:

Step-by-step explanation:

2x + 10 + 4x + 20 = 180 ( Adjacent Angles )

6x + 30 = 180

6x = 150

x = 150 / 6  =  25

2(25) + 10 = 50 + 10 = 60

4(25) + 20 = 100 + 20 = 120

Answer 2

AnswEr:-

Here we have to find the value of x.

Concept Used:-

Linear pair:- The sum of angles which made a straight angle is always 180°.

And here also,

Angles 2x+10 and 4x+20 are in linear pair.

Therefore,

$\tt \mapsto(2x + 10)\degree + (4x + 20)\degree = 180\degree\\ \\ \tt(by \: linear \: pair) \\ \\ \tt\mapsto2x\degree + 4x\degree + 10\degree + 20\degree = 180\degree \\ \\ \tt\mapsto6x\degree + 30\degree = 180\degree \\ \\ \tt\mapsto6x\degree = 180\degree - 30\degree \\ \\ \tt\mapsto6x \degree= 150\degree \\ \\ \tt\mapsto \: x = \cancel\frac{150\degree}{6\degree} \\ \\ \tt\mapsto \: x = 25$

Therefore the required value of x is 25.
