Answer:
Step-by-step explanation:
Solve by substitution. Solve the second equation for x:
Insert the value of x into the first equation:
Solve for y. Simplify multiplication using the distributive property:
Subtract 190 from both sides:
Isolate the variable to find its value. Divide both sides by -29:
Now take the value of y and insert back into either equation to solve for x:
Subtract 6 from both sides:
Divide both sides by 5:
Therefore, the solution to the system is .

Hello!
In an isosceles trapezoid, both angles on each side of the base are congruent.
∠z ≅ 75°
∠y ≅ ∠x
Because of this, we can get the angle measure for z easily:
m∠z = 75°
