What is measure of angle R?
1 answer:
You have three options, all of them work.
sin(angle) = opposite/hypotenuse
cos(angle) = adjacent/hypotenuse
tan(angle) = opposite/adjacent
You are already given the length of the lines, so all you can is to take the inverse of whatever you choose to get the angle.
(5/13) = 22.62
(12/13) = 22.62
(5/12) = 22.62
sin(angle) = opposite/hypotenuse
cos(angle) = adjacent/hypotenuse
tan(angle) = opposite/adjacent

2n - 7 × 1 = 15 × 3
2n - 7 = 45
2n = 45 + 7
2n = 52
n = 26
