Around swimming pool has a circumference of 66feet. carlos wants to buy a rope to put across the diameter of the pool. the rope cost $.45 per foot, and cralos needs 4 feet more than the diameter of the pool. how much will carlos pay for the rope

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°.

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
