Answer:
Step-by-step explanation:
Total interior angles in a triangle=180 degrees
That is: 3x + 10 + 5x - 1 + x =180
9x+9=180
9x=180-9
9x=171
x=171/9
x=19
Therefore
Angle A =67 degrees
Angle B= 94 degrees
Angle C = 19 degrees
The answer is c. 117 degrees
Answer:
Bye
Step-by-step explanation:
Figure it out yourself
The answer is 200 because you multiply 20x12 you get 200
You can multiply opposite sides, like so:
y*7 = 8*3
7y = 24
y = 24/7
