Answer:
D
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanθ =
=
, then
θ =
(
) ≈ 60° ( to the nearest degree )
Answer:
No
Step-by-step explanation:
Let's use the Pythagorean Theorem. For those of you that don't know, it is
.
11 is the bigger side in this case, so our formula would go like this:
.
We now calculate to see if this is true.
25 + 36
121
Therefore, the answer is wrong.
Answer: 11x - 8y = -9
Step-by-step explanation:
Subtract it by terms.
8x - (-3x) = 11x
-4y - (4y) = -8y
-4-5= -9
order it
11x - 8y =-9
√20 = 4.47213
√20 = 4 (nearest integer)
√20 = 4.5 (nearest tenth)
