A ramp is being built and attached to a building to help with deliveries. The angle that the bottom of the ramp makes with the ground is 37.2°. Find the measure of the other acute angle.

52.8 degrees

Step-by-step explanation:

A ramp is a right angle meaning on of the angles has to be 90 degrees. Every triangle adds up to 180 degrees to subtract 180 by 90 and 37.2 to get 52.8 degrees.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
