Tanα=h/x, tanß=h/(x+88)
solving both for x
x=h/tanα, x=h/tanß-88, since x=x
h/tanα=h/tanß-88
h/tanß-h/tanα=88
(htanα-htanß)/(tanα*tanß)=88
h(tanα-tanß)/(tanα*tanß)=88
h=88(tanα*tanß)/(tanα-tanß)
Since α=32 and ß=22...
h=88(tan32*tan22)/(tan32-tan22)
h≈85.3 feet

Step-by-step explanation:
Remark
You have to guess what the question is. I'm assuming that it is either the black triangle to the blue one or the blue one to the black one. Be careful when you post a question to see if you have included a question.
Answer
<em>Ratio of blue to black</em>
The distance of the left most point of the blue triangle to the y axis is 3. The same point on the black one is 1
blue/black = 3/1
<em>Ratio of black to blue</em>
ratio of the black triangle to the blue one is 1/3
The answer will depend on the question. Notice that the two answers are reciprocals.
Answer:
29
Step-by-step explanation:
9+5=14+5=19+5=24+5=29
In order to find the area of the semicircle, or the shaded region, we just have to find the area of the entire circle and divide it by 2. The formula for the area of a circle is
. With the given diameter of 12, we can deduce that the radius is 6.
Area of Semicircle = (
/2)
Area of Semicircle = (3.14 x 36/2)
Area of Semicircle = (3.14 x 18)
Area of Semicircle = 56.52
Hope this helps!
