Answer:
55.4 ft²
Step-by-step explanation:
The special triangle with angles 30°-60°-90° has side lengths in the ratios ...
1 : √3 : 2
The area of the triangle can be found using the area formula ...
A = 1/2bh
where b is the base and h is the perpendicular height.
__
<h3>sides</h3>
The longest side is given as 16 ft. This corresponds to "2" in the ratio, so the other two sides have lengths ...
8 ft, 8√3 ft
__
<h3>area</h3>
These area the perpendicular sides of the triangle so, work well to find the area.
A = 1/2bh
A = 1/2(8√3 ft)(8 ft) = 32√3 ft²
A ≈ 55.4 ft²
The area of the triangle is about 55.4 square feet.
Answer:
C. 10 s.
Step-by-step explanation:
When the hammer reaches the ground the height is 0 m, so:
-t - 2t + 30 = 0
-3t = -30
t = -30/-3
= 10 seconds.
Answer:
n > 3
Step-by-step explanation:
Given
3n + 6 > 15 ( subtract 6 from both sides )
3n > 9 ( divide both sides by 3 )
n > 3
Answer:
C
Lucky guess if this is wrong i am truly sorry.
