Area of a Square Formula: A = s²
- <em>s</em> is a side length
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
A = 124 in²
<u>Step 2: Solve for </u><em><u>s</u></em>
- Substitute in variables [Area of a Square Formula]: 124 in² = s²
- [Equality Property] Square root both sides: s = 2√31 in
- Approximate: s = 11.1355 in
Answer:
A) 30°
Step-by-step explanation:
All triangles angles add always to 180°, so we have two already 75° + 75° = 150° thus the angle is 30°
