The correct answer is C. Aimee used the Associative and Commutative properties to put numbers that are easy to add next to each other.
Answ(2,4)
Step-by-step explanation:
7 and 9
7^2=49
9^2=81
49+81=130
The measure of angle θ = 7pi/6. To convert this to degrees, substitute pi with 180 degrees. Pi is always equal to 180 degrees.
θ becomes: 7 x 180/6
Therefore, θ = 210 degrees.
And, to solve for sin θ, you can directly input sin (210) in the calculator.
Thus, sin θ = sin (210) = -0.5 or -1/2
You have to match up the sides. So you have two x values of 7, and one of -3, so that suggest that the x value you're looking for is -3. You have two y-values of 1, and one of -4, so i'd say look for a negative four. My answer would be A. (-3,-4)
