Since we know that the measure of angle 3 is 72 we now also know that angle 2 equals 72 because they are congruent. So 72 + 72 = 144. 180 - 144 = 36. Meaning angle 1 equals 36 degrees.
The answer is C Opposite Leg over the Adjesent Leg you can remember this because of SOH CAH TOA That means Sin = Opp/Hyp Cos = Adj/Hyp Tan = Opp/Adj
Answer: 2x5−3x4−8x3+12x2
Step-by-step explanation:
(2x2−3x)(x3−4x)
=(2x2+−3x)(x3+−4x)
=(2x2)(x3)+(2x2)(−4x)+(−3x)(x3)+(−3x)(−4x)
=2x5−8x3−3x4+12x2

Triangle JKL was rotated 90° counterclockwise and then refrected across the line y = -4.
That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.
If you had 2a+3a, then it would simplify to 5a
Similarly, 2b+3b = 5b
Or you could have 2ab+3ab = 5ab
The key is that the variable portions must match up to be able to add them.
