Answer:
24
Step-by-step explanation:
BD=DC
5x-26=2x+1
5x-2x=1+26
3x=27
x=9
BC=2x+1
=2*9+1
BC =19
so AB=AC-BC
AB=43-19
AB=24
Roughly 24, but there's possibly like nine more. I got 24 without getting too confused
Answer:
1.) -5
2.) -4
Step-by-step explanation:
For number 1, you sub in -2 for x.
2 multiplied by -2 is -4, minus 1 = -5.
For the second one, sub in 5 for x.
-5 + 1 = -4.
Hi there!
In order to solve, we need to use the formula for the area of a circle, and the angle given to find the area of the sector. Then, subtract the area of the triangle to find the area of the segment. We would use the equation : A = x/360 (pi * r^2) - 1/2(b * h). We need to plug in 90 for the angle measurement, 8 for the radius, and 8 for both the base and height.
WORK:
A = 90/360 (pi * 64) - 1/2(64)
A = 1/4(64pi) - 32
A = 16pi - 32 = ~ 18.3ft^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
