What is the value of k? (4k+5) (6k+10) 115

An exterior angle is equal to the sum of the two opposite inside angles.

The picture shows an exterior angle of 115 degrees.

It's two opposite inside angles are the two equations.

This means:

(4k +5) + (6k+10) = 115

Combine like terms:

10k + 15 = 115

Subtract 15 from both sides:

10k = 100

Divide both sides by 10:

k = 100/10

k = 10

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
