Recap: Adjacent Angles

Part of the Angles section of Coddy's Geometry journey. Lesson 6 of 62.

Challenge

Easy

∠AVM measures 55° and the whole angle ∠AVB measures 95°.

$A 95 degree angle split into 55 degrees and x degrees$

Find x, the measure of ∠MVB.

Try it yourself

x + 55 = 95

Solve for x
