Answer:
x=15
Step-by-step explanation:
(3x-10)+(2x+25)=90
5x+15=90
5x=75
x=15
(2x+25) = 55°
(3x-10)=35°

Answer:
w = 19/4
Step-by-step explanation:
Solve for w:
-27 + 17 (w - 4) + 3 w = 0
17 (w - 4) = 17 w - 68:
17 w - 68 + 3 w - 27 = 0
Grouping like terms, 17 w + 3 w - 68 - 27 = (17 w + 3 w) + (-27 - 68):
(17 w + 3 w) + (-27 - 68) = 0
17 w + 3 w = 20 w:
20 w + (-27 - 68) = 0
-27 - 68 = -95:
20 w + -95 = 0
Add 95 to both sides:
20 w + (95 - 95) = 95
95 - 95 = 0:
20 w = 95
Divide both sides of 20 w = 95 by 20:
(20 w)/20 = 95/20
20/20 = 1:
w = 95/20
The gcd of 95 and 20 is 5, so 95/20 = (5×19)/(5×4) = 5/5×19/4 = 19/4:
Answer: w = 19/4
Answer:
m∠B = 31°
Step-by-step explanation:
First, find the measure of angle ACB by subtracting its supplement from 180 degrees:
180 - 113 = 77
m∠ACB = 77°
Then subtract both m∠A and m∠ACB from 180 degrees, since the interior angles of a triangle always add to 180°:
m∠B = 180° - 72° - 77°
m∠B = 31°
