Answer:
See below
Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
Answer:
A. point B (-11,7) Point C (11,-7)
Step-by-step explanation:
We know the sum of all the angles in a quadilateral is equal to 360. so,
it would be: 360 - (74+93+117)
= 360 - 284
= 76 degrees
So, Your final answer is 76 degrees.
