Using Equations to Solve for Unknown Angles

Elena and Diego each wrote equations to represent these diagrams. For each diagram, decide which equation you agree with, and solve it. You can assume that angles that look like right angles are indeed right angles. Elena: x = 35. Diego: x + 35 = 180. Elena: 5 + w + 41 = 180.

7.1.4: Solving for Unknown Angles

Summary. We can write equations that represent relationships between angles. Figure 7.1.4.3. The first pair of angles are supplementary, so x + 42 = 180. The second pair of angles are vertical angles, so y = 28. Assuming the third pair of angles form a right angle, they are complementary, so z + 64 = 90.
