Question

Geometry help needed!

Answer 1

Answer: 43

Work Shown:

y+47 = 90

y = 90-47

y = 43

Answer 2

Given :-

• AB and CD are straight lines segments.

To find:-

• The value of "y" .

Answer:-

Firstly as we know that the measure of a straight line is 180° . The given line is made up of 3 angles , which are 47° , y° and one right angle i.e. 90°.

So the sum of all these angles will be 180° as these are the angles of a straight line.

So that,

`\implies 47^o + y^o + 90^o = 180^o\\`

`\implies 137^o + y^o = 180^o \\`

`\implies y^o = 180^o-137^o\\`

`\implies \underline{\underline{ y = 43}} \\`

Hence the value of y is 43 .

and we are done!
