Acyclist rides his bike at a speed of 18 miles per hour. what is this speed in feet per second? how many feet will the cyclist travel in 15 seconds? in your computations, use the fact that 1 mile is equal to 5280 feet. do not round your answers.

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
