Answer:
B. 18
Step-by-step explanation:
Given:
There are two chord in the circle.
These chords are divided in two segments.
Segments of 1 chord is 21 and 6.
Segments of 2 chord is x and 7.
Now by using Intersecting Chord Theorem which states,
"When two chords intersect each other inside a circle, the products of their segments are equal."
Hence from above theorem we can say that;

Hence the Value of x is 18.
Answer:
30°, 45°, and 105°
Step-by-step explanation:
Find the value of x
2x + 3x+ 7x = 180
12x = 180
x = 180/12
x=15
Get the value of the angles
2x = 2(15)
3x= 3(15)
7x= 7(15)
The measure of the angles are 30°, 45°, and 105° respectively.
There are 14 girls in HR 218 because 24/12 is 2, meaning that the ratio needs to be multiplied by 2/2 in order to figure out what 7/12 is. 7/12*2/2 is 14/24, therefore there are 14 girls in HR 218.
Answer:
Step-by-step explanation:
(p²)²+2²
(p²+2)²-2p²2
(p²+2)²-4p²
(p²+2)²-(2p)²
(p²+2-2p)(p²+2+2p)
