Answer:
Step-by-step explanation:
2 tan(60) = 2 * (sqrt(3)/2 = sqrt(3)
1 + tan^2(60) = 1/cos^2(60) = 1//1/4 = 4
The answer is going to look a little convoluted but it should be correct.
The answer so far is sqrt(3) /4
sin(60) = sqrt(3)/2
of the 4, two is needed to get sqrt(3)/2
So far then we have sin(60)/2
If we multiply by 2 as in (sin(60)/2) we get just sin(60)
2* sqrt(3) /4 then = 2 sin(60)
Answer:
x = 300
Step-by-step explanation:
25% of x = 75
(25x/100) = 75
25x = 7500
x = (7500/25)
x = 300
Thenks and mark me brainliest :))
Omg thx for the points ;)
D i am pretty sure.... I hope this helps have a good day!
Answer:
56sq. cm
Step-by-step explanation:
Area of a trapezoid = 1/2(a+b)h
a and b are the parallel sides
h is the height of the trapezoid
Find the f=diagram attached. from the diagram
a = 9cm
b = 5 + 9 + 5 = 19cm
h = 4cm
Substitute
Area of the trapezoid = 1/2 * (9+19)*4
Area of the trapezoid = 1/2 * 28 * 4
Area of the trapezoid = 28 * 2
Area of the trapezoid = 56sq. cm
