Answer:
A = 157 in^2
Step-by-step explanation:
First, we need to get the radius, we can do this by dividing our given diameter by 2.
20/2 = 10
Now, we have our radius of 10 inches.
Formula for Area of a Semi Circle: (1/2)(pi(r^2)
Input values.
(1/2)(3.14(10^2)
Solve.
(1/2)(3.14(100)
(1/2)(314)
1/2(314) = 157
Finally, we have our result which is 157 inches^2.
Answer:
14^2+48^2=2500 sqrt2500= 50 c=50
Step-by-step explanation:
7. y=4/3x-2
8. y= -1/2x+5
9. x= -1 undefined
The value of the angle y of the given line transversal is 45°
<h3>What is the transverse line theorem?</h3>
The transverse Line theorem states that If two parallel lines are cut by a transversal, then, Alternate Exterior Angles are congruent. If two parallel lines are cut by a transversal, then corresponding angles are congruent. Two lines cut by a transversal are parallel IF AND ONLY IF corresponding angles are congruent.
Now, from the question we are told that line m is parallel to line n which we see in the attached image.
Now, from the transverse Line theorem as defined above, we can say that the sum of y° and 135° will be equal to 180°due to both being opposite interior angles. Thus;
y = 180 - 135
y = 45°
Correct question is;
Find the value of y if m∥ n.
