Question

When Ranim started karate, her highest kick went 110 degrees from the ground. Her instructor asked her to practice until her highest kick goes 155 degrees from the ground. Which equation will tell us the measure of the additional angle, a, that Ranim's kick needs to go to reach 155 degrees from the ground?

155−110=a
155+110=a
180−110=a
155+90=a

Answer 1

To find the additional angle needed. Subtract the starting angle from the needed angle:

Answer: 155 - 110 = a
