Answer:Hi,
Let the number be x
Twice the number is 2x
Five less than twice the number is 2x-5, which is given as 9
Therefore, 2x-5 = 9
or, 2x = 9+5
or, 2x = 14
or x=7
Thus the number is 7.
Cheers

Step-by-step explanation:
The value of all the angles in a triangle add up to 180.
So to find x do 180-(66+52)
The angle opposite of x is the same value as x
X+E or X+Z are both equal to 180.

Step-by-step explanation:
Maybe it was (7-2x)/-4+2<-x then times 4 both sides

Answer:
8/15
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that ...
Tan = Opposite/Adjacent
The side opposite angle B is side AC. The side adjacent to angle B is side BC. So, the tangent of angle B is ...
tan(B) = AC/BC = 8/15
