Answer:
B (2,-3) A (7,-8)
Step-by-step explanation:
they are just the same points but in the negative side of the x-axis
Angle A= angle B
angle C= angle a(2)
a+a+2a=180 (since all triangles equal 180 degrees)
180=4a
180/4
a=45
angle A and angle B both equal 45 degrees. Angle C equals 90 degrees.
Answer:
I = 575.0, .08, 3.0
I= 138, i think
Step-by-step explanation:
All angles in a triangle add up to 180 degrees.
We are finding the value for both y's (they are congruent) so I'll just plug in the answers to the problem.
Let's start with 54.
54*2=108
108+72=180
The answer is then A, 54 degrees
