The value of angle x is 127 degrees.
<h3>How to find angles?</h3>
The angle x can be found as follows:
Angle on a straight line is 180 degrees.
Therefore, the sum of 53 degrees and x degrees is 180 degrees.
Therefore,
53 + x = 180°(sum of angles on a straight line)
subtract 53 from both sides of the equation
53 - 53 + x = 180 - 53
x = 127°
Therefore, the angle of x is 127 degrees.

Step-by-step explanation:
(a)55+80+x=180 (angles inside the triangle)
135+×=+180
x=180-135
x=45
<u>Answer:</u>

<u>Step-by-step explanation:</u>
We know from the question that the student earned $12.50 <em>per hour</em>.
Using this information, we can say that if the student worked for <em>h </em>hours, they would make a total of 12.50 × <em>h </em>dollars.
We also know that the total money they earned is $2500.75.
∴ Therefore, we can set up the following equation:

From here, if we want to, we can find the number of hours worked by simply making <em>h</em> the subject of the equation and evaluating:
<em>h </em>=<em> </em>
= 200.6 hours
Answer: C (4,7)
Points are labeled as (x,y)
If the unknown point is 4 units away from the origin on the x axis, x will be 4
If the unknown point is 7 units away from the origin on the y axis, y will be 7
Therefore (4,7)
Your answer should be C. 3x^3√2
