Answer:
The correct set of hypotheses is
: d=80 degrees
: d>80 degrees
Step-by-step explanation:

: d>80 degrees
Answer:
c. Cos 52 = 17/c
Step-by-step explanation:
sin(x) = cos(90-x)
When the expression has only one KIND of a variable, and also only one kind of a lonely number.
A lonely number is a number that has no variable next to it. Their need to be one kind of it.
Example of a simple expression:-
16c + 3
Trial and error
(3x-5)(x+1)
woo, good first guess
anywa, the real legit way is
3x^2-2x-5
find
-2=a+b such that a is a factor of 3 and b is a factor of -5
-2=3+-5
so split it up
3x^2+3x-5x-5
factor
(3x)(x+1)+(-5)(x+1)
undistribute
(3x-5)(x+1)
tada
160+160+160+160=640 and then divide it by 2
