Question

The measures of Z1 and 22 are 30% and 45% of the sum of the angle measures of the triangle. Find

the value of x.

Answer 1

45 degree or 25%

Explanation:

sum of angles of triangle= 180 so

`180*(30)/(100)=54`-----> angle 1

(note: 30% is equal to
`(30)/(100)`)

`180*(45)/(100) =81`------> angle 2

lets add angle 1 and 2 together

54+81=135

now lets subtract it from 180 to get the remained angle

180-135=45 and if you want it in % so you just get 100%-(30%+45%)= 25%
