Answer:
x=32°
Step-by-step explanation:
2x+3x+20=180 co interior angle
5x=180-20
x=160/5=32°
Answer: x=10
Step-by-step explanation:
1/5(x-2)=1/10(x+6)
1/5x -2/5=1/10x + 6/10
+2/5 +2/5
1/5x =1/10x + 1
-1/10 -1/10
1/10x= 1 divide both sides by 1/10
x= 10
Answer:
x=75
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the side of the large triangle.
42 50
------ = ----------
42+63 50+x
42 50
------ = ----------
105 50+x
Using cross products
42(50+x) = 50*(105)
2100+42x = 5250
Subtract 2100 from each side
2100-2100+42x = 5250-2100
42x =3150
Divide by 42
42x/42 = 3150/42
x = 75
