A is a vertical angle to 51 and is the same.

A = 51

C is a vertical angle to 53 and is the sane. c = 53

51 + c + d need to equal 180:

51 + 53 +d = 180

d + 104 = 180

d = 180-104

d = 76

d and b are vertical angles, so b = d = 76

a = 51

b = 76

c = 53

d = 76

Dmitry_Shevchenko [17]
Because the triangle is a right angle, the hypotenuse is the square root of the sum of the legs squared or the square root of (20 ^2 + 15^2) or 25. The distance wayne computed was the distance from Ferris to Dunlap or 15 plus the distance from Dunlap to Butte or 20 or 35 miles all together. The difference of 35 and 25 is 10

Solve the proportion for the variable 6/y= 9/33
NeX [460]

Answer: y=22

Step-by-step explanation:

1. Multiply by <em>y</em> both sides of the equation, as following:

\frac{6y}{y}=\frac{9y}{33}\\\\6=\frac{9y}{33}

2. Now you must multiply by 33 both sides of the equation, as following:

6*33=\frac{9y}{33}*33\\198=9y

3. Now you must divide both sides of the equation by 9. Therefore, you obtain:

\frac{198}{9}=\frac{9y}{9}\\y=22
