Answer:
20√3 cm
Step-by-step explanation:
Altitude of an equilateral triangle splits it into 2 equal right triangles, it bisects the base and the angle opposite to the base.
<u>Let the altitude be x. Then as per Pythagorean theorem:</u>
- x² = 40² - (40/2)²
- x²= 1600 -400
- x²= 1200
- x= √1200
- x= 20√3 cm
<u>Correct choice is</u> the second one
Answer:
1. 11.8x9.8=115.64 115.64/2=57.82 (57.82Inches)
2. 12x5=60 60/2=30 (30m)
3. 25x9=225 9x9=81 81/2=40.5 225-40.5=184.5 184.5/92.25 (92.25ft)
