Answer:
Measure of angle 4 is 115°
Step-by-step explanation:
First, we want to find the measure of angle 2, because the measure of angle 2 is equal to angle 4. When 2 straight lines cross each other, the angles formed are always equal to the angle right across from it.
Find angle 2 by setting up an equation:
This is basically saying that angle 1 plus angle 2 equals 180°. In a half turnaround, the angle is 180°. Angle 1 and 2 make up a half turnaround.
Solve the equation:
Combine the 2 x's to get 2x.
Subtract 50 from both sides.
Divide both sides by 2.
Since x=65, plug 65 into x in the measure of angle 2 (x+50).
65+50=115.
Since Angle 2 is equal to angle 4, angle 4 is also 115.
Answer:
Question 1 - she will make $10.50 and still owe you $5.25 because 0.35 x 30 = 10.25
question 2 - for this im not sure because the 2nd, 3rd and 4th wont work so it should be the first but I’m not sure what that equation is saying
question 3 - 29 glasses need to be sold
Because we are dealing with area, we have to square the difference of the 2 polygons.40 / 15 =
<span>
<span>
<span>
2.6666666667
</span>
</span>
</span>
<span>
<span>
<span>
2.6666666667^2 = </span></span></span>
<span>
<span>
<span>
7.1111111111
</span></span></span>
<span><span><span>
</span>
</span>
</span>
So, the 40 yard polygon has <span>
<span>
7.1111111111</span>times the area of the 15 yard polygon.
</span>
<span />
180/3 for square yards
multiply answer by $15 for the answer.....hope this helps :)
