We have been given that angle FED with angle F=90 degree, ED=36, and FE=22. We are asked to find the unknown angles and the unknown side length of the triangle.
We will use sine to solve for angle D as:
Therefore, measure of angle D is 37.7 degrees.
Now, we will find measure of angle E using angle sum property.
Therefore, measure of angle E is 52.3 degrees.
We will use Pythagoras theorem to solve for side FD as:
Therefore, length of side FD is approximately 28.5 units.
Answer:
63
Step-by-step explanation:
First we need to find the area of each pizza in square inches with pizza with the round shape, then calculate the difference.
The formula of area of circle is:
Area = π
As we know, medium pizza has 12 inch diameter and small pizza has 8 inch diameter.
- <u>For 12 inch diameter, radius = 6
</u>
A = π = 36π
- <u>For 8 inch diameter, radius = 4
</u>
A = π = 16π
Difference of the two area: 36π - 16π = 20π
by putting the value of π, the difference is
A=20 * 3.14 => 63
x < 4
given x - 1 < 3 ( add 1 to both sides )
x < 4
or x ∈ ( - ∞, 4 ) ← in interval notation
Answer:
g=2160
Step-by-step explanation:
multiply both sides by 12
180*12=2160
g=2160
