Answer:
#1 x = 31°
#2 x = 125°
Step by Step Explanation:
#1
- By the theorem of intersecting secants outside of the circle, we have:
#2
- By the theorem of intersecting chords, we have:
Insert y and you get
X=0
Then insert x and you get
Y=-5
A= 42in²
P = 2l + 2w so
(21 x 2) + (2 x 2)
42 + 4 = 46
46 = 21 by 2
Now let's do 6 and 7
(6 x 2) + (7 x 2)
12 + 14 = 26
46 > 26
so 21 by 2 has greater P (perimeter)
Exponents are hard but think about it like addition, that number tells you how many times to add that number to itself. To write the equation put the number and then the exponent on the top right of that number. Your welcome!
