Angle NBW is 34 so do the math
Answer:
<h2>L.A. = 384 cm²</h2><h2>S.A. = 640 cm²</h2>
Step-by-step explanation:
Lateral Area:
We have four congruent triangles with base b = 16cm and height h = 12cm.
The formula of an area of a traingle:
Substitute:
Surface Area:
In the base we have the square with side s = 16cm. The formula of an area of a square:
Substitute:

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
2v + 3v + 75 = 180
<u>Step 2: Solve for </u><em><u>v</u></em>
- Combine like terms: 5v + 75 = 180
- Isolate <em>v</em> term: 5v = 105
- Isolate <em>v</em>: v = 21
The answer is x = -2 +- sqrt 7
