Answer:
A
Step-by-step explanation:
Given
8 - 2x + 6x = 24 , that is
8 + 4x = 24 ( subtract 8 from both sides )
4x = 16 ( divide both sides by 4 )
x = 4 → A
sin(x) = 2cos(x)
tan(x) = 2
tan⁻¹[tan(x)] = tan⁻¹(2)
x ≈ 63.4
sin(2x) = sin[2(63.4)]
sin(2x) = sin(126.8)
sin(2x) ≈ 0.801
Answer:
(2703/64)^3
Step-by-step explanation:
hello :
(5 1/8 x 5 3/8)^3 = (51×53/8×8) ^3 = (2703/64)^3
I will say there are two ways to solve this problem. The first is, you can use your calculator and calculate it to see which is the closest to 2. The second way is divide it and here is how you do it:
1 is just 1
15/16 = 16 goes into 15 for less than one
17/8 = 8 goes into 17 for more than two so you can rewrite it as

63/33 = 33 does not go into 63 for two
So the answer is 17/8
If your teacher is asking "which of the following can be used to prove the triangles congruent?" then I agree with your statement that it's "none of the above". We simply don't have enough information to determine if the triangles are congruent or not. If we wanted to use SAS, then we'd have to know if EB = BD was true. If we wanted ASA, then we'd have to know that A = C. If we wanted AAS, then we'd have to know that E = D.
In short, you have the correct answer. Nice work.
