Answer:
0.6
Step-by-step explanation:
Given the trapezoid formula:
1/2(b1+b2/2)xH
We are given the numbers for the trapezoid:
0.3,0.9,1
To solve this here is what we are going to do.
1/2(0.9+0.3)x1
So add 0.9+0.3=1.2
Then Divide 1.2/2=0.6
So multiply 0.6 x 1=0.6
0.6 is your answer
Step-by-step explanation:
x,y} = {-7/25,2/5} that os the enter
Answer:
C
Step-by-step explanation:
A) not true. Sin A = some decimal
Cos 720 = 1
D) That means that d is not true either. not true
B) Sin55 = cos55 is not true either only sin(45) = cos(45) is true. So B is not true.
That leaves C. I think if you check it, you'll find it is right. sin(A) = cos(90 - A)
