Since the legs are the same length, we know that the remaining two angles must be the same.

120+2x=180
2x=60
x=30

Final answer: x=30 degrees

The circle shown has center o and radius 4. what is the area of the shaded region?
Vlad [161]

The ratio of his savings: expenses = 7: 5

So, total of the ratio is = 7 +5 =12

His savings will be 7/12* allowance

His expenses will be 5/12 * allowance

We know that the allowance that he gets is $3

His savings = 7/12 * allowances  

His savings = 7/12 * 3

His savings = $7/4 or 1 ¾  

Now, we convert the 7/4 (or 1 ¾) into a decimal.  

1 ¾ when converted is decimal is 1.75

His Savings = $1.75

Two angles are supplementary if their sum is​ 180°. the larger angle measures five degrees more than four times the measure of a
wlad13 [49]
Let x represent the smaller angle.
Let y represent the larger angle.

The problem states that the larger angle measures five degrees more than four times the measure of the smaller angle.
With this given information, we can create the following equation.

y=4x+5

Also, they a supplementary, meaning that they add up to 180. We can create another equation.

x+y=180

Since we have two linear equations and we want to find the solution, we have a system of linear equations. Let's solve this system by using the substitution method.

Substitute y=4x+5 into x+y=180

x+y=180

After substituting, you get

x+4x+5=180

Now, combine the x's

5x+5=180

Subtract both sides by 5

5x=175

Divide both sides by 5.

x=35

Now, we can solve for y using the equation x+y=180 since we know the value of x.

35+y=180

Subtract both sides by 35.

y=145

The smaller angle has a measure of 35 degrees and the larger one has a measure of 145 degrees. Have an awesome day! :)
