Answer:
Sally is 30 and Suki is 20
Step-by-step explanation:
x = Sally's age
y = Suki's age
x = 10 + y
(x - 5) + (y - 5) = 40
x = 30, y = 20
10 or u could do 25 divided by 2.5 is 10
Answer: Um, The answer is 1, 12, –3.
Step-by-step explanation:
Answer:
Apply trigonometric function for triangle ABC:
7.
sin A = BC/BA = 6/7.2 = 0.83
A = arcsin(0.83) = 56.44
8.
tan B = AC/BC = 4/6 = 0.67
B = arctan(0.67) = 33.69 deg
Hope this helps!

Use the formula S = xr.
Note: I am using x in place of theta since there is no theta symbol on my keyboard.
We want to find S, the arc of the given circle.
S = (1 rad)(17 units/rad)
Notice that both rad cancel out.
Note: rad is radians for short.
S = 17 units
