Question

(x+42)
3x
please help

Answer 1

Given:-

• A right angle is given to us.
• It is made up of two angles (x+42)° and 3x°.

To find:-

• The value of " x " .

Solution:-

Here the sum of the two unknown angles will be 90° as they are the angles which make up 90° . So that;

`\implies x^o + 42^o + 3x^o = 90^o \\`

`\implies 4x^o = 90^o - 42^o \\`

`\implies 4x^o = 48^o \\`

`\implies x =(48)/(4) \\`

`\implies \boxed{ x = 12} \\`

Hence the value of x is 12 .

and we are done!
