7x + 5x = 180
12x = 180
x = 15
Therefore, the 2 angles equal (7*15) and (5*15) which equals
105 degrees and 75 degrees
What are you doing if your graphing the points for the first one you start at -7 on the y axis and go up 3 and over tho the left by 1
For the second one you start at 1 on the y axis and go up 3 over the right 1
Answer:
5x+8
Step-by-step explanation:
X=72 cause 180-(51+57) so 180-108 and the triangle is acute cause all of the angle measures are below 90 degrees.
So your answer is
x=72
Acute Triangle
