Answer:
x ≈ 32.4
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between angle, adjacent side, and hypotenuse:
Cos = Adjacent/Hypotenuse
cos(72°) = 10/x
x = 10/cos(72°)
x ≈ 32.4
Answer:
6:16
Step-by-step explanation:
To find the answer you do 3x_=6 which the missing number is 2, so you do 8x2=16 because whatever you multiply the first number by you have to do the same to the second number in fractions, ratios, etc.
The line y=3 is a vertical line. Thus, another line that is perpendicular to y=3 is a horizontal line. If this horiz. line passes thru the point (5, -6), then x = 5 is the desired equation.
They're equal length, so add 18 and 18 to get 36.
