student A give to little step the beging to get pointe G Student A is wrong
The answer here is D, <span><span>Percent = 90%, Amount = unknown, Base = 70</span>
We can solve this by using what we know. The first step is to note that 90 is the percent (since it has the percent sign). In addition, we know that 70 is the base (since we're taking a percent of 70). That gives us our answer of </span> D, <span>Percent = 90%, Amount = unknown, Base = 70.</span>
26 all you gotta do is add!
The measure of angle C is 89 degrees.
<u>Step-by-step explanation:</u>
The given polygon ABCD is a quadrilateral.
<u>The property of a quadrilateral :</u>
The sum of the consecutive angles add to 180°.
In this quadrilateral, the angles B and C are consecutive angles. So, the sum of angle B and angle C is equal to 180 degree.
Given that,
- The measure of angle B = 2x+3
- The measure of angle C = 2x+1
<u>To find the value of x :</u>
m∠B + m∠C = 180
(2x+3) + (2x+1) = 180
4x + 4 = 180
4x = 180 - 4
4x = 176
x = 176/4
x = 44
<u>To find m∠C :</u>
m∠C = 2x + 1
⇒ 2(44)+1
⇒ 88+1
⇒ 89°
The measure of angle C is 89 degrees.
The numerator should be 8x
