Answer:
C
Step-by-step explanation:
Answers:
Angle T = 79 degrees
Angle V = 14 degrees
=========================================================
Work Shown:
T + V = 93
(2x+85) + (5x+29) = 93
7x+114 = 93
7x = 93-114
7x = -21
x = -21/7
x = -3
This x value is used to find each angle mentioned.
- Angle T = 2x+85 = 2(-3)+85 = -6+85 = 79 degrees
- Angle V = 5x+29 = 5(-3)+29 = -15+29 = 14 degrees
As a check, T+V = 79+14 = 93 which confirms our answers.
Answer:
<h2>43.3cm²</h2>
Step-by-step explanation:
Area of a Triangle = Base * Height * 1/2
Base = 5
Height = 4.33
Area of a Triangle = 5 * 4.33 * 1/2
Area of a Triangle = 10.825
There are four triangles.
Surface Area = Area of a Triangle * Number of Triangles
Surface Area = 10.825 * 4
Surface Area = 43.3cm²
