Answer:
The answer is (a) ⇒ tanx = sinx/cosx
Step-by-step explanation:
∵ (sinx)(cosx)(tanx) = (sinx)(cosx)(sinx/cosx) = sin²x
∵ sin²x = 1-cos²x
∴ L.H.S = R.H.S
∴ (sinx)(cosx)(tanx) = 1 - cos²x
The formula for the area of a trapezoid is a=1/2(b1+b2)h
So 10*5 = 50 *4 = 200 then divided by 2 is 100 so the answer is 100
Answer:
33 1/3 percent smaller
Step-by-step explanation:
The number a exceeds the number b by 50 percent.
a = b + b*.5
a = b(1.5)
Divide by 1.5
a/1.5 = b
2/3a =b
We want to find (a-b)/a to find the percent decrease
(a-2/3a)/a *100percent
(1/3a)/a* 100 percent
1/3 * 100 percent
33 1/3 percent smaller
