Question

Helpppp
Pleaseeeeeeeeeeeeeee

Answer 1

`x=34\\`

m<A = 138.5º

m<B = 41.5º

Explanation:

These angles added together should equal 180

`x+7.5+2x+70.5=180`

`3x+78=180`

Subtract 78 on both sides

`3x=102`

Divide by 3 on both sides

`x=34`

Now to find the angles we fill in x

Angle A

`2(34)+70.5\\68+70.5\\138.5`

Angle D

`34+7.5\\41.5`
