Step-by-step explanation:
Area of isoceles triangle is
where b is the base and h is height.
Let draw a altuide going through Point D that split side FE into 2 equal lines. Let call that point that is equidistant from FE, H.
Since it is a altitude,it forms a right angle. So angle H=90.
Angle H is equidistant from F and E so
FH=11
EH=11.
The height is still unknown.
We can use pythagorean theorem to find side h but we need to know the slanted side or side DF to use the theorem.
Using triangle DFH, we know that angle H is 90 and angle F is 34. So using triangle interior rule,Angle D equal 56.
- We know side FH=11
- We know Angle D equal 56
- We are trying to find side DF
- We know angle H equal 90
We can use law of sines to find side DF
Plug in the numbers
sin of 90 =1 so
Side df is about 13.3 inches.
Since we know our slanted side is 13.3 we can set up our pythagorean theorem equation,
is approximately 7.5 so dh=7.5 approximately.
Now using base times height times 1/2 multiply them out
Answer:
Step-by-step explanation:
If our ratio is apple juice to orange juice, then the proportion will be
If we are looking for how much orange juice she needs if she uses 32 ounces of apple juice, then 32 goes on top of a new ratio and x goes on bottom:
That's the proportion. If you need to solve it, cross multiply to get
8x = 128 so
x = 16 ounces of orange juice
