Sin x = square root (2) / 2
In order for us to get for cos x and tan x, first we need to know what
Hypotenuse, Adjacent, and Opposite sides.
sin x = opposite / hypotenuse.
adjacent = square root (hypotenuse^2 - opposite^2)
adjacent = square root (2^2 - square root(2)^2)
adjacent = square root (4 - 2)
adjacent = square root (2)
cos x = adjacent / hypotenuse
tan x = opposite / adjacent..
cos x = square root (2) / 2
tan x = square root (2) / <span>square root (2) = 1
So, </span>cos x = square root (2) / 2 and tan x<span> = 1</span>
Answer:
x = 87
Step-by-step explanation:
37 + 56 = 93
triangles always equal to 180
180 - 93 = 87
Answer:
Step-by-step explanatiArea of Composite Shapes. Composite shapes are shapes that have a combination of 2-D shapes. To find the area of composite shapes you just need to break down the shape into individual pieces and calculate their separate pieces then add them back together again to find a total areaon:
Answer: 24.6 inches
Step-by-step explanation: Since it's a rectangle, and not a rectangular prism, that means it's 2D. Length is the long sides on the top and bottom, and width is the shorter sides on it's left and right. So since there's two of each, just do 8.1 + 8.1 + 4.2 + 4.2 and you have your answer!
Answer:
f(3) = 3
Step-by-step explanation:
f(x) = 2x^2 – 5x
Let x = 3
f(3) = 2(3)^2 - 5(3)
= 2*9 -15
= 18-15
