The legs of an isosceles triangle are congruent; they have the same length, so if one leg measures 2 m, the other leg also measures 2 m.
2m + 2m + b = 7.5 m
b + 4 m = 7.5 m
b = 3.5 m
The length of the base is 3.5 m.

Answer:
Perpendicular
Step-by-step explanation:
[1] We need to find the slopes of both lines! First, we will put them into standard form and then solve.
Standard form: y=mx+b
(1) 10x + 2y = 4
(subtract 10x from both sides)
2y = -10x + 4
(divide both sides by 2)
y = 5x+2
The slope is 5
(2) 5y - x = -5
(add x to both sides)
5y = x - 5
(divide both sides by 5)
y = x - 1
The slope is one-fifth
[2] Then, we need to determine if they are parallel, perpendicluar, or neither.
- If they are parallel they will have the same slope
- If they are perpendicular they will have exact opposite slopes
() Line 1 has a slope of 5 and line two has a slope of one-fifth. These are exact opposites so the lines are perpendicular.

Answer:
21.04
Step-by-step explanation:
Start by adding the hundredths category. 0.09 + 0.05 = 0.14, this means that your hundredths column will be a 4, and you will carry the 1 over to the tenths.
Now add your tenths. 0.0 + 0.9 + 0.1 = 1.0, which means that your tenths column is a 0. Carry the 1 over to the whole numbers.
Now add your whole numbers. 7 + 13 + 1 = 21. Combine your terms and you get 21.04
Answer:
225 square meters
Step-by-step explanation:
Area of a square:
A = w², where w is the width of the square
Plug in values:
A = 15m²
A = 225 square meters
