Question

Can I get some help plz?

Answer 1

`angles \: of \: triangle \: add \: up \: to \: {180}^(0) \\ {(2x + 10})^(0) + {(2x)}^(0) + {90}^(0) = {180}^(0) \\ 4x = {(180 - 90 - 10)}^(0) \\ 4x = {80}^(0) \\ x = {20}^(0)`

Answer 2

X=20 degree

Explanation:

∆A+∆D+∆O=180

2x+10+2x+90=180

collect like terms

2x+2x=180-100

4x=80

(4x)/4=(80)/4

x=20 degree
