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:
<h2>The answer is 615 m²</h2>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius
From the question
r = 14 m
π = 3.14
The area of the circle is
A = 3.14 × ( 14 ) ²
= 3.14 × 196
= 615.44
We have the final answer as
<h3>615 m² to the nearest whole number</h3>

<u>The transformations include:</u>
This is a dilation by a scale factor of 3 and then translation 2 units left and 2 units up.
<u>The transformation applied to the point U:</u>
- U(-4,2) → U'(-4*3 - 2, 2*3 + 2) = U'(-14, 8)
