The answer is x is less than and equal to 8. Treat the sign as an equal sign.
The product of two and b to the power of the two.
You want to write this equation in the form (x+...)(x+...) (maybe with a minus sign). To do this, find numbers that, when multiplied, give 16, and when added give -10.
What whole numbers give 16?
1*16 and -1*-16
2*8 and -2*-8
4*4 and -4*-4
Which of these solutions, when changed into a sum, give -10?
Try them one by one and find it is:
-2-8 = -10.
So (x-2)(x-8) is the factorization!
This is really a bit of trial and error, but since most of the time the assignments deals with whole numbers, there aren't that many possibilities.

Answer:
m∠C = 35°
Step-by-step explanation:
Data
From the figure, it can be seen that a right triangle is formed where CA is the hypotenuse and CD is one of the legs.
From definition:
cos(C) = adjacent/hypotenuse
cos(C) = CD/CA
cos(C) = 23/28
m∠C = arccos(23/28)
m∠C = 35°
