X/49 = 21/x
x^2 = 21(49) = 1029
x = √1029 = 32.1
x = 32.1
Answer:
11.1%
Step-by-step explanation:
The percentage change in a value can be computed from ...
%change = ((new value)/(old value) -1) × 100%
= ((8500/9559) -1) × 100%
= (0.8892 -1) × 100%
= -11.08%
The value of the car decreased about 11.1% in the first year.
Mean because the mean is an average. That gives an overall understanding of what the entire class did.
Sine is the opposite to the hypotenuse
so if sinA=0.6, suppose the opposite is 6, the hypotenuse is 10
now find the other leg by using a²+b²=c²: 6²+b²=10², b=8
sinB=8/10=0.8
Answer: They are similar but not congruent.
