Answer:
d= 90 degrees
e= 99 degrees
f= 81 degrees
Step-by-step explanation:
To find d, you know that the other side is equal to 90. Because two sides that are opposite of each other must be equal to 180, you do 180-90 which is 90 to get d. Therefore, d=90 degrees. 99 degrees and e are alternate interior angles so that means they have to be the same. Because f is on the other side of 99 degrees and two sides that are opposite of each other must equal 180 degrees, you have to do 180-99 which is equal to 81 degrees. Therefore, d=90 degrees, e=99 degrees, and f=81 degrees

Recall the double/half angle formulas:
We're given 
, and since 
is between π/2 and π, we expect 
to be negative. So from the Pythagorean identity, we find
Also, we know 
will fall between π/4 and π/2, so both 
and 
will be positive. Then we find
and it follows that
2.5 x 10 = 25 m^2
1.5 x 10 = 15 m^2
2 x 10 = 20 m^2
0.5 x 1.5 x 2 = 1.5 m^2 (2 times)
Total = 63 m^2
So just fill in 63.
Answer:
I = Prt
Substitute the given information. Remember to write the percent in decimal form. I = (500)(0.06)(3)
Simplify. I = 90
Check your answer. Is $90 a reasonable interest earned on $500 in 3 years? In 3 years the money earned 18%. If we rounded to 20%, the interest would have been 500(0.20) or $100. Yes, $90 is reasonable.
The simple interest is $90.

Answer:
The answer is 4.75
Step-by-step explanation:
Since six months is 28.50 then 1 month is equal to x
28.50: 6 months
x : 1 month
After this you cross multiple so u divide by 6 both side to get 4.75
6x/6: 28.50/6
x=4.75
