Which best explains whether or not all isosceles triangles are similar?
All isosceles triangles are similar. Two angles within each triangle are always congruent.
All isosceles triangles are similar. The triangle sum theorem states that the sum of the angles in a triangle is 180°. Therefore, the third angle can always be determined.
All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
All isosceles triangles are not similar. Given only the vertex angle of an isosceles triangle, there is not enough information to determine the measures of the base angles. Therefore, it is not possible to determine if the base angles of one isosceles triangle are congruent to the base angles of another.
Answer:
C: All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
Step-by-step explanation:
An Isosceles triangle is one that 2 of it's sides are equal and thus two of its angles are congruent which means they are equal.
Now, another Isosceles triangle may not necessarily be similar to another one because the congruent angles in one Isosceles triangle may not be the same with that of another Isosceles triangle.
Thus, correct answer is option C

Jada was measuring the dimensions of her new closet. The area of the closet is 8 1/6 square feet and the width of the closet is 3 1/2 What is the length of her closet?
Answer: 2 1/3 feet
Step-by-step explanation:
Area of closet = 8 1/6 feet ²
Width of the closet = 3 1/2 feet
Length of the closet = Unknown
We should note that:
Area = Length × Width
Length = Area / Width
Length = 8 1/6 ÷ 3 1/2
= 49/6 ÷ 7/2
= 49/6 × 2/7
= 7/3
= 2 1/3 feet
The length is 2 1/3 feet

A mountain climber ascends a mountain to its peak. The peak is 14,090 ft above sea level. The climber then descends 490 ft to meet a fellow climber. Find the climber’s elevation above sea level after meeting the other climber.
13,600 ft
14,580 ft
–13,600 ft
9,190 ft
Answer:
13,600 feet above sea level
Step-by-step explanation:
The climber was at 14,090 feet above sea level, and then they went 490 feet closer to sea level to meet the other climber. Since they’re moving closer to sea level and you want to know how far *above* sea level they are, subtract 490 from 14,090. 14,090-490=13,600 feet above sea level

1x+2y=5 find four solutions
Answer:
Simplifying
1x + 2y = 5
Solving
1x + 2y = 5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
1x + 2y + -2y = 5 + -2y
Combine like terms: 2y + -2y = 0
1x + 0 = 5 + -2y
1x = 5 + -2y
Divide each side by '1'.
x = 5 + -2y
Simplifying
x = 5 + -2y

Benjamin is painting a fence that has an area of 192.4 square feet. He uses 3/5 gallon of paint to paint 1/4 of the fence. How many gallons will he need to do the entire fence?
Answer: 2 2/5 gallons
Step-by-step explanation:
We are provided with the information that Benjamin uses 3/5 gallon of paint to paint 1/4 of the fence.
The number of gallons that he needs to do the entire fence will be gotten by dividing the gallon used by the fraction of fence painted. This will be:
= 3/5 ÷ 1/4
= 3/5 × 4/1
= 12/5
= 2 2/5 gallons
Therefore, 2 2/5 gallons will be needed to do the entire fence.
