Since angle C is not 90 degrees, it's one of the acute angles
in the right triangle.
(The side adjacent to angle C ) divided by (hypotenuse)
is the cosine of angle C .
(adjacent) / (10 inches) = cos(40 degrees)
Multiply each side by (10 inches):
Adjacent side = (10 inches) x cos(40) =
(10 inches) x 0.766 =
7.66 inches (rounded)
Answer:
Option D
Step-by-step explanation:
Collect all like terms and Calculate
-10x-7x= -17x
20-54= -34
Divide
-17x < -34
x>2
Answer:
I presume that 10x would be on the x axis to the right of 0.
-7y would be on the y axis under 0. Therefore in between -6 and -8
You might know this but very important
X to the decks (horizontally/straight across) and Y to the sky (vertically/ up and down)
Answer: 100.
Justification.
A perfect square is a number that can be expressed and the square of an integer.
In this case, 10^2 = 100, so 100 is a perfect square.
It is a good idea to memorize the first perfect squares. I recommend you memorize the squares of the numbers from 1 to 14. That will help you a lot in some standardized tests,which requires to answer some quesitons fast:
