Mathematics

Oliga [24]3 years ago

Angle R can be solved using the inverse sine button on a calculator. Sine is y/r so opposite leg over the hypotenuse. For r, the opposite leg is 5cm and the hypotenuse is 13. The inverse sin button looks like sin^-1. Punch that in the calculator (make sure in degree mode). Punch the inverse sin and then 5/13 and you should get 22.62°

2(9n - 6) + 52 = 2(7n + 8)
STatiana [176]

Step-by-step explanation:

2×9n=18n

2×-6=-12

52-12+18n= 38 +18n

2×7n=14n

8×2=16

14n+16

38+18n=14n+16

subtract 14n from 14n and 18n

38+4n=16

subtract 38 from 38 and 16

4n=-22

divide each side by 4

n= -5.5
