ron and francine are building a ramp for performing skateboard stunts, as shown in the accompanying diagram. the ramp is 7 feet long and 3 feet high. what is the measure of the angle x, that the ramp makes with the ground, to the nearest tenth of a degree

7 plus threeis equal to same like 10 answer is 10

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

14

step-by-step explanation:

14 x 3 = 42
