What is measure of angle R?

1 answer:

4 0

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°

(3x+4)^3=2197 solve this equation

Burka [1]

(3x + 4)³ = 2197

Taking the cube root in this case is easier, although we can do it the extended way which is complicated.

$\sqrt[3]{(3x+4)^3}$ = $\sqrt[3]{2197}$
3x + 4 = 13

Now solve normally.

subtract 4
3x + 4 = 13
-4 -4

3x = 9
Divide by 3 to isolate 3

$\frac{3x}{3} = \frac{9}{3}$
3 and 3 cancels out

x = 3
