Answer:
AB = 12
Step-by-step explanation:
Since the triangle is isosceles, the sides AB and BC are congruent. Then you have ...
4x = 2x+6
2x = 6 . . . . . . subtract 2x
4x = 12 . . . . . .multiply by 2
The side AB has length 12.
The length of the line segment here is 13.
Distance Formula:
√((x₂ - x₁)² + (y₂ - y₁))
√((5 - 0)² + (0 - 12)²) = 13
The area of a triangle could be determined using the following formula

plug in the numbers



a = 126
The area of the triangle is 126 square meters
The surface area of the rectangular prism with the dimensions that are stated is: 384 in.²
<h3>What is the Surface Area of a Triangular Prism?</h3>
Surface area = perimeter of base × height of prism + 2(base area)
= (s1 + s2 + s3)L + 2(1/2bh)
Given the following:
- side of base (s1) = 6 in.
- side of base (s2) = 8 in.
- side of base (s3) = 10 in.
- Length of prism (L) = 14 in.
- Triangular base length (b) = 6 in.
- h = 8 in.
Surface area = (6 + 8 + 10)14 + 2(1/2 × 6 × 8)
Surface area = 384 in.²
