Answer:
64.1°
Step-by-step explanation:
tan x = opp/adj
tan x = 20/9.7
tan x = 2.0619
x = tan^-1 2.0619
x = 64.1°
There are special properties to certain right triangles.
A 3-4-5 triangle will always be a right triangle. 9 divides into 3, and 15 divides into 5, so you can use ratios to find b.
Since 9 divides into 3, we will use this to set up proportions for the missing value:

Cross multiply the fractions.

Divide both sides by 3.

The missing value is
12.
Answer:
x>-2.5
Step-by-step explanation:
Answer:
The separated values of x and y from the given equation is 
Step-by-step explanation:
Given equation is 
Now to find the separated values of x and y with the given equation.
Now find the value of x and so we have to separate the value x from the given equation



Therfore 
Now find the value of y and so we have to separate the value y from the given equation





Therefore 
The separated values of x and y from the given equation is
