Answer: 
Step-by-step explanation:
1. Based on the information given in the problem, you can draw the right triangle shown in the figure attached.
2. Keeping the informationn given in the problem, you can calculate the angle that the sum makes with the ground (
)as you can see below:

Where:

3. Then:


Multiply all 4 an the answer is gonna be the area
25, 7*4 = 28 32-28=4 and 42/6=7*3 = 21 + 4 = 25
Answer:
O is the center of the circle with radius IE(=ID=EF)
Step-by-step explanation:
Join all 3 points D, E, F, forming the triangle DEF.
Let the midpoint of EF be M and the midpoint of ED be N. (first picture)
Join point I to E, D and F.
Since IN is both an altitude and median to triangle EID, then triangle EID is an isosceles triangle, and IE=ID
similarly, we see that IE=IF.
conclusion: IE=ID=EF.
