It is always isosceles because it can be proved as follows:
The perpendicular bisector dissects the triangle into two, and it is the common side. Then each side of the bisector is 90 degrees, and the bisected to two equal sides, so the two dissected triangles are congruent, hence the original triangle is isosceles.
Answer:
24
Step-by-step explanation:
Split the shape into 2 so you get a triangle and a rectangle.
Find area of triangle:
1/2 x a x b = 1/2 x 3 x 4
= 6 square feet
Find area of rectangle:
b x h = 6 x 3
= 18
Add both together
18 + 6 = 24
1st is to make the numbers into ratios. Basically taking the two numbers and putting them in the middle. I’ll do the 1st 15:36.
Next you put it into a fraction: 15/36

Answer:
17 ft
Step-by-step explanation:
The triangle on the bottom left is a right triangle.
a² + b² = c²
(8 ft)² + (15 ft)² = (RQ)²
64 ft² + 225 ft² = (RQ)²
(RQ)² = 289 ft²
RQ = 17 ft
Answer: all the ones that do not have a negative sign in front easy.
