Answer:
14
Step-by-step explanation:
we can use sin(30⁰) to solve this and the units will be 14

Step-by-step explanation:
The answer would be about 66. Ps . I hate that website. It's for common core learingl it is soooo boring !
In a circle, the measure of an inscribed angle is half the measure of the intercepted arc.
∠BCD = arc BAD/2 ⇒ arc BAD = 2*∠BCD = 2*100 = 200°
arc BCD = 360° - arc BAD = 360° - 200° = 160°
∠d = arc BCD/2 = 160/2 =
80°
Answer: The height of the palm tree is 21 feet.
Step-by-step explanation:
We can use a ratio to solve this:
Actual height to shadow for both objects. The fraction equivalents must be equal.
6/8 = x/28 . Cross multiply
6(28) = 8x
168 = 8x Divide both sides by 8 (8's "cancel" on the right)
168/8 =8x/8
21 = x . This gives us the tree's height as 21 feet.
<em>Another way to solve this is to use the ratios, but simplify the first fraction</em>
<em>6/8 = 3/4</em>
<em>Then multiply the length of the shadow by 3/4</em>
<em>3/4 × 28 = height</em>
<em>28÷4 = 7 7 × 3 = 21</em>
<em>21 feet= the height of the palm tree.</em>
