In triangle stu, s = 9 cm, t = 15 cm, and m angle u = 37 degrees. find u.

1.) A 39 degrees

2.) B 36 degrees

3.) B 43.8

4.) B 96.68

5.) C 169.3 ft

6.) C 9.5 cm

7.) X = 8.4 cm

8.) X= 2879.4 m

Step-by-step explanation:

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
