Question

(0.3x + 64) degrees (0.1 + 32) degrees find the value of x

Answer 1

`x=-15`

Explanation:

Complete question : In a right triangle other two angles are
`(0.3x+64)\textdegree\ and\ (0.1x+32)\textdegree` find the value of
`x`.

In a right angle the third angle is
`90\textdegree`

we know that

Sum of angle in a triangle
`=180\textdegree`

`(0.3x+64)+(0.1x+32)+90=180\\\\0.3x+64+0.1x+32+90=180\\\\0.4x+96+90=180\\\\0.4x+186=180\\\\0.4x=-6\\\\`

Dividing
`0.4` both sides

`(0.4x)/(0.4)=(-6)/(0.4)\\\\x=(-60)/(4)\\\\x=-15`
