Answer:
For the first test the score was 89 and on the second test it was 96
Step-by-step explanation:
To find the answer we make the situation into an algebraic expression.
192 divided by 2 is 96; hence
Hello.
To find the value of the angle x, you need to use the Law of Sines. The Law of Sines states, sin A / a = sin B / b = sin C / c.
We are given sin A = 42 degrees, side a = 22 cm, and side b = 12 cm. We can change x, to angle B in this case.
sin (42) / 22 = sin B / 12 (multiply both sides by 12)
12 sin (42) / 22 = sin B
sin^-1 B = 12 sin (42) / 22
sin B = 21.4063..
The measure of angle x is equal to about 21.4 degrees.
Answer:
Formula for the area of a circle;
A = π
Where 'π' represents pi(22/7 or 3.14), and 'r' stands for the radius being squared.
But, we are given a <u>diameter</u> instead of a <u>radius</u>.
So to find the radius of the diameter we must find 1/2(half) of the diameter:
Diameter/2 = Radius
Plug in what we know:
D/2 = R
8/2 = R
4 = R, <u>4 is our radius</u>.
Now we use this radius in our formula;
A = π
A = 3.14(4^2) ← (The symbol ' ^ ' means to the power of.)
A = 3.14(16)
A = <u>50.24 centimetres</u> is the area for this circle.
