Problem 24
<h3>Answer: w = 120</h3>
-----------------
Work Shown:
We have an isosceles triangle. The angles opposite the congruent sides are congruent. These are the base angles each 30 degrees. The missing angle is w. The three angles add to 180
(angle1)+(angle2)+(angle3) = 180
30+30+w = 180
60+w = 180
60+w-60 = 180-60 ... subtract 60 from both sides
w = 120

Problem 25
<h3>Answers:</h3><h3>x = 6.5</h3><h3>y = 5</h3>
-----------------
Work Shown:
The angle marks are all the same, so the three angles are congruent to one another. We consider this an equiangular triangle. Any equiangular triangle is also equilateral, meaning all three sides are the same length.
So,
2x-5 = 8
2x-5+5 = 8+5 ... add 5 to both sides
2x = 13
2x/2 = 13/2 ... divide both sides by 2
x = 6.5
and also,
y+3 = 8
y+3-3 = 8-3 ... subtract 3 from both sides
y = 5

Answer:</h3>
A=160 m
<h3>
Solution:</h3>
- The formula for the Area of a rectangle is:
- A=LW
- In the above formula, L stands for the length and W stands for the width.
- We are given:
- L=16 m
- W=10 m
- We are asked to find the area of the rectangular pool.
- The operation that we're going to use here is:
- Multiplication.
- Multiply:
- A=16*10
- A=160 m

Problem Example :
Given: HF || JK; HG ≅ JG
Prove: FHG ≅ KJG
Answer: A. ∠FGH ≅∠KGJ because vertical angles are congruent.
Answer:
Step-by-step explanation:
So we just want to get y by itself
2x - 4y = 8
4y = 2x - 8
y = (2/4)x - 2
y = (1/2)x - 2
In this form the y intercept and slope are easy to see. the slope is m and y intercept is b.
slope = 1/2
y intercept = -2
