Answer:

135

Step-by-step explanation:

Okay so we know that all angles in tringle sums up to 180

Therefore ∠2 = 180 - ∠1 - ∠3 = 180 - 35 - 100 = 45deg

We also know that angles on a straight line add up to 180deg as well

Therefore ∠4 = 180 - ∠2 = 180 - 45 = 135deg

In this image, the two angles (equations) form a right angle, which is 90°. You combine these equations: 4y-7+3y-1. When you combine like terms, you get 7y-8. You set this equal to 90°. 7y-8=90. Solve for y, and you get y=12.

One geometry question <br> Please help me with this!!!!

otez555 [7]

Answer:

∠ XAZ = 50°

Step-by-step explanation:

The measure of the circle = 360°

Given arc XYZ = 230°, then

arc XZ = 360° - 230° = 130°

The tangent- tangent angle XAZ is one half the difference of the intercepted arcs, that is

∠ XAZ = $\frac{1}{2}$ (230 - 130)° = 0.5 × 100° = 50°
