Subtract 3 from both sides
4x = 51 - 3
Simplify 51 - 3 to 48
4x = 48
Divide both sides by 4
x = 48/4
Simplify 48/4 to 12
<u>x = 12</u>
Answer:
10x
20
Step-by-step explanation:
expression
10x
for x = 2
10 (2)
20
The answer is -45 and 36 because -45+36=-9
Answer:

Step-by-step explanation:
To work out x is easy as they are corresponding angles x will also equal 50
however to work out y you just need to minus 180 and 50 to give 130

Measure of angle 5 i.e. m∠5 = 50°
<h3>
What is measurement of an angle ?</h3>
The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.
<h3>
How to find angle measurement ?</h3>
As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.
In the question,
Let given angle is ∠8.
Given, ∠8 = 50°
Now, according to vertical angle property
∠5 = ∠8
therefore, ∠5 = 50°
Thus, m∠5 = 50°
