Are these possible lengths for a triangle: 47,28,70. Explain your reasoning
Yes, the two smaller sides added together are still bigger than the largest side by itself

Are these possible lengths for a triangle: 40, 40, 80. Explain your reasoning
No because the two shorter angles has to be bigger than the larger one. They cannot be equal.

Angle A = 2x + 3 and Angle B = x form a right angle. Solve for x and find each angle measurement.
2x + 3 + x = 90
3x + 3 = 90
x = 29
Angle A = 61 Angle B = 29

Angle A and C are vertical angles. Angle A = 11y-36 and Angle B = 63. Find the measure of Angle A.
11y-36 = 63
11y = 99
y = 9
Angle A: 63 degrees.
