Anna does sit-ups to get ready for her first triathlon. when she starts, she does a sit-up every 2 seconds. but, as she gets tired, each sit-up takes longer and longer to do. is the number of sit-ups anna does proportional to the time she spends doing them?

answer:

yes

step-by-step explanation:

because the time it takes her to do a sit-up goes up like the amount she does

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°.
