Complementary angles total 90°.
∠A + ∠B = 90°
∠A + 60° = 90° . . . . substitute the given information
∠A = 30° . . . . . . . . . subtract 60° from both sides of the equation
The angle that is complementary to ∠B measures 30°.
The surface area of a triangular prism with the 3 sides slant height as 14 the base width as 8 and the base height as 6.9 is 155. 705 in²

What is the surface area of a triangular prism?</h3>
The surface area of a triangular pyramid is the total area of all it's faces.
The properties of a triangular prism are;
- It is bounded y three lateral triangular faces meeting at one vertex.
- It has all its faces as triangles
<h3>
How to determine the surface area</h3>
Surface area = Base Area + 1÷2 (perimeter × base height)
But base area = 1÷2 (base side × height)
Base area = 1÷ 2 (8 × 14) = 0.5 × 112 = 56 in²
Perimeter = sum of all the sides = 14 + 8 + 6.9 = 28. 9 in
Base height = 6. 9in
Surface area = 56 + 1 ÷ 2 ( 28.9× 6. 9) = 56 + 0.5 × 199.41 = 56 + 99. 705 = 155. 705 in²
Surface area = 155. 705 in²
Therefore, the surface area of the triangular prism is 155. 705 in²

Answer:
18.75pages
Step-by-step explanation:
158 = 8p + 12
158 - 12 = 8p
146 = 8p
P = 146/8
P = 18.75
Answer:
Option A is correct.
Step-by-step explanation:
Between B and C, the value of height (y) remains constant, as shown as a horizontal line on the graph.

Answer:
C. Yes, because every x-value corresponds to exactly one y-value.
Step-by-step explanation:
The list of x-values is {-1, 0, 2, 4, 7}. We note that no two are the same, so this is a functional relation.
The set of ordered pairs is a function because each x-value corresponds to exactly one y-value.
