Question

Can someone explain how to get the answer I’m confused on how to solve

Answer 1

x = 29

(x + 3)° = 32°

(x - 1)° = 28°

(x + 1)° = 30°

Explanation:

• (x + 3)° + (x - 1)° + (x + 1)° = 90°

• -> (x + x + x +3 -1 + 1)° = 90°

• -> (3x + 3)° = 90°

• -> 3x + 3= 90

• -> 3x = 90 - 3

• -> 3x = 87

• -> x = 87/3

• -> x = 29

• -> (x + 3)° = (29 + 3)° = 32°

• -> (x - 1)° = (29 - 1)° = 28°

• -> (x + 1)° = (29 + 1)° = 30°

Answer 2

x=29

Explanation:

The square notation indicates 90 degrees.

90=(x+3)+(x-1)+(x+1)

90=3x+3

87=3x

x=29
