What is the measure of ∠R

77 degrees

Step-by-step explanation:

The triangles are similar so all the angles would be congruent.

63 + 40 + r = 180

103 + r = 180

-103 -103

r = 77

I hope this helps have a good day!

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
