To find this you would do 50/100 which equals .5
-x + 4 = 2x + 1
add x to both sides
4 = 3x + 1
subtract 1 from both sides
3 = 3x
dived 3 from both sides
1 = x
Question:
What is the m∠ACB in the circle shown below?
Answer:
45
Step-by-step explanation:
So we know it is <u><em>less than a right angle</em></u> and it is not a obtuse angle it is less than 90 degrees. 45 is less, 90 is equal(<em>not what we are looking for</em>) , 120, is greater, and 180 is greater which leaves us to our answer 45.
He should use the Pythagorean Theorem to find the missing length.
Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.
So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5
Therefore, the radius of circle L is 5 feet.

<u>Midpoint and Distance Between two Points</u>
Given two points A(x1,y1) and B(x2,y2), the midpoint M(xm,ym) between A and B has the following coordinates:


The distance between both points is given by:

Point (5,7) is the center of circle A, and point (1,-1) is the center of the circle B. Given both points belong to circle C, the center of C must be the midpoint from A to B:


Center of circle C: (3,3)
The radius of C is half the distance between A and B:


The radius of C is d/2:

Center: (3,3)
Radius:
