Find the measure of each angle: ∠3 and ∠4 are supplementary. m∠3 = 5x + 22 and m∠4 = 7x + 2.

Step-by-step explanation:

Since ∠3 and ∠4 are supplementary it means the the sum of their angles is equal to 180°

To find the angles add both ∠3 and ∠4 and equate it to 180° solve for x and substitute it into their various expressions

That's

∠3 + ∠4 = 180

5x + 22 + 7x + 2 = 180

12x + 24 = 180°

12x = 180 - 24

12x = 156

Divide both sides by 12

x = 13

So for ∠3

∠3 = 5x + 22

∠3 = 5(13) + 22

= 65 + 22

∠3 = 87°

For ∠4

∠4 = 7x + 2

∠4 = 7(13) + 2

= 91 + 2

∠4 = 93°

Hope this helps you

Step-by-step explanation:

We know that the sum of supplementary angle adds up to 180 °

So,

Collect like terms

⇒

Add the numbers

⇒

Move 24 to right hand side and change it's sign

⇒

Subtract 24 from 180

⇒

Divide both sides of the equation by 12

⇒

Calculate

⇒

Value of x = 13

Now, substituting / Replacing the value of x

⇒

⇒

⇒

Again,

⇒

⇒

⇒

m ∠ 3 = 87

m ∠ 4 = 93

Hope I helped!
