Question

Given that the measure of angle 3 is 75o. What is the value of x if the measure of angle 7 is (x + 40) ?

Number only (no words or variables)

Answer 1

• <3 and <7 are corresponding angles so they are equal

`\\ \tt\longmapsto x+40=75`

`\\ \tt\longmapsto x=75-40`

`\\ \tt\longmapsto x=35`

Answer 2

• The value of x is 35°.

Explanation:

We know that:

• ∠3 = 75°
• ∠3 = ∠7 (Corresponding angles)
• ∠7 = x + 40

Work:

• => 75 = x + 40
• => 75 - 40 = x
• => 35 = x

Hence, the value of x is 35°.

Hoped this helped.
