Question

A triangle has two congruent angles and one unique angle. The solution to the system of equations below represents the relationship between the angle measures. What are the measures of the angles in the triangle

2x+y=180
x−y=30 there is three angles
Enter the correct answers in the boxes.

Answer 1

Answer:

X and Z are congruent angles as both are wqual to 70⁰

Y is the unique angle measuring 40⁰

Step-by-step explanation:

Adding both the equations we get

3x = 210

x = 70

x- y =30

70 -y = 30

y = 40

Please mark me as brainliest.

x+ y + z = 180

70+ 40 + z = 180

z = 70
