Answer:
83.5 degrees
Step-by-step explanation:
first, find x:
x+5x-13+4x=180
10x=193
x=19.3
Then, substitute that value for c:
5*19.3-13
=83.5 degrees
Answer:
x > -3
Step-by-step explanation:
-2x < 9 - 3
-2x < 6
-x < 3
x > -3
Answer:
b
Step-by-step explanation:
The sum of angles in a triangle is 180°. Therefore,
x - 11 + 48 + 90 = 180
x + 127 = 180
x = 53°
You can answer this problem in two different ways: the first being (17 - 5) * x, and the second being 12 * x.
