Basically what you need to do is add up the expressions, 7x and 3x and make it equal to 90 degrees. Then solve for x. Substitute the value of x for each expression to determine the values of each angle.
7x + 3x = 90
10x = 90
X = 90/10
X = 9.
Angle 1 = 7(9) = 63 degrees
Angle 2 = 3(9) = 27 degrees.
Check
63 + 27 = 90
90 = 90.
Really bad according to the BLS, the average secondary school teacher in the U.S. earns an annual salary of $56,760. A 40-hour work week employee would have to earn $27.28 per hour to earn as much over the course of a year.
Hey!
Let's solve this together.
5x+1 = 1+x2
Possible Answers: {5,4,3,2}
Lets start with 5.
5(5)+1 = 1+2(5)***
25+1 = 1+10
26 ≠ 11
So, 5 is NOT the answer.
Now, 4.
5(4)+1 = 1+(4)2
20+1 = 1+8
21 ≠ 9
So, 4 is NOT the answer.
Now, 3.
5(3)+1 = 1+(3)2
15+1 = 1+6
16 ≠ 7
So, 3 is NOT the answer.
Lastly, 2.
5(2)+1 = 1+(2)2
10+1 = 1+4
11 ≠ 5
So, 2 is NOT an answer.
So, the answer is: None of the above. None of them can be answers because none of them make the statement true.

We know that
circumference=2*pi*r
for r=5 cm
circumference=2*pi*5-----> 31.4 cm
if 360° (full circle) has a length of------------> 31.4 cm
225°-----------------------------> X
X=225*31.4/360-----> X=19.625-----> x=19.63 cm
the answer is
19.3 cm
