Answer:
CPB
Step-by-step explanation:
acute is less than 90 degrees and right is 90 degrees and obtuse is over 90 degrees
Hey there!
2(2y - 12) = 0
2(2y) + 2(-12) = 0
4y - 24 = 0
ADD 24 to BOTH SIDES
4y - 24 + 24 = 0 + 24
SIMPLIFY IT!
4y = 0 + 24
4y = 24
4y/4 = 24/4
SIMPLIFY IT!
y = 24/4
y = 6
Therefore, your answer should be:
y = 06 (Option B.)
Good luck on your assignment and enjoy your day!

Given:
tan x = 3/y
cos x = y/z
Because tan x = sin(x)/cos(x), therefore
sin x = tan(x)*cos(x)
= (3/y)*(y/z)
= 3/z
Answer: a) sin x = 3/z
Answer: A. Use Pythagorean Theorem to prove that KL is equal to c.
=========================================================
Explanation:
If we could show that KL = c, then we can tie together the following pairs of segments
- EG = KM = a
- GF = ML = b
- EF = KL = c
Then we'd use the SSS congruence theorem to prove the triangles are congruent. The last step is to use CPCTC to conclude that angle EGF is a 90 degree angle.
Keep in mind that we need to know the actual numeric values of 'a' and 'b' to be able to determine the value for c. So without the numbers, the Pythagorean theorem isn't really useful; however, I can see where your teacher is going with this line of logic. Your teacher is effectively just laying out a basic outline more or less.

Notes:
- SSS = side side side
- CPCTC = corresponding parts of congruent triangles are congruent
