Answer: 43°

Step-by-step explanation:

The degree of a triangle adds up to 180. We are given an angle of 47 and there is a right angle of 90

We now have 90 + 47 + a = 180

137 + a = 180

a = 43

Answer:

The measure of angle a is 43 degrees.

Step-by-step explanation:

viktelen [127]

Step-by-step explanation:

Total money = 20

Entrance fee = 1.75

Food = 2.50

Ride = 1.05

Amount spend = 1.75 + 2.05 = 3.8

Left for rides = 20 - 3.8 = 16.2

So rides = 16.2 ÷ 1.05 = 15

I think atleast 15 rides

Answer:

a. 36.25 ft

b. 45 ft

Step-by-step explanation:

GIVE YOUR ANSWER IN FEET !!! as the problem statement says.

not in inches. when you use the scale factor with inches, you get inches as result. then you need to convert them to feet.

how many inches in 1 ft ?

12 !

so, you need to divide your results by 12 to get the feet.
