Answer:
1st ∡ = 15.5°
2nd ∡ = 77.25°
3rd ∡ = 87.25°
Step-by-step explanation:
1st ∡: x
2nd ∡: y
3rd ∡: z
Equations we can create from data given in problem:
y + z = 5x
z = 5x + 10
We have enough expressions to create an equation:
x + 5x + 5x + 10 = 180
11x = 170
x = 15.5
y = 5(15.5) = 77.25
z = y + 10 = 87.25
Answer:
Step-by-step explanation:
Answer:
20 so the fractions would be 3/4=15/20 and 9/10=18/20
Step-by-step explanation:
because 4 x 5 = 20 and 10 x 2 = 20
Subtract the numbers.
10 - 8 = 2
Divide it to the smaller number:
2 / 8 = 0.25
Multiply by 100:
0.25 * 100 = 25%
360 miles in 4 hours. Find the rate by dividing 360 by 4.
360/4=90MPH
90MPH * 10hrs = 900 miles.
