The measure of ∠7 is 47°. Angle 7 is a vertical angle to angle 5
Suppose the measure of ∠6 is represented represented by (2x - 5), the equation that can be use to solve for x is 42 + 2x = 180
The value of x is 69
<h3>Vertical opposite angles</h3>
Vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.
Vertical opposite angles are congruent. Therefore,
a. ∠5 ≅ ∠7 (vertical angles)
Therefore, angles 5 and 7 are congruent angles.
∠7 = 47°
b. Suppose ∠6 = 2x - 5 . let's find x
Therefore,
∠5 + ∠6 = 180(angle on a straight line)
The equation to solve the above is as follows:
47 + 2x - 5 = 180
42 + 2x = 180
2x = 180 - 42
2x = 138
x = 138 / 2
x = 69

1. Isolate the y. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, multiply 12 to both sides
-y/12(12) = 6(12)
-y = 6(12)
-y = 72
Isolate the y. Divide -1 from both sides
-y/-1 = 72/-1
y = -72
-72 is your answer for y

2. Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
x/4 = 8
First, multiply 4 to both sides
x/4(4) = 8(4)
x = 8(4)
x = 32
32 is your answer for x

Divide 858 by 18 to get 47.6 > simplify > 48 feet
<span>The <u>correct answer</u> is:
$64.
Explanation<span>:
We will mulitiply the first two numbers first.
We will first write 1200 as a fraction by putting it over 1:
1200/1 * 8/100.
We now multiply straight across: (1200*8)/(1*100) = 9600/100 = 96.
Now we will multiply this by the last fraction. Again we will make the whole number, 96, a fraction by placing it over 1:
(96/1)*(240/360).
Again we multiply straight across: (96*240)/(1*360)=23040/360.
When we divide this out, we get 64.</span></span>
