angle abc and ghk are equal by given. you set them equal and solve like this.
6x+2=5x-27+3x+1 combine like terms
6x+2=8x-26 subtract 6x from both sides
2=2x-26 add 26 to both sides
28=2x divide both sides by 2
x=14
measure of abc would be 6x+2 or 6(14)+2 or 86 degrees
Answer:
40.2
Step-by-step explanation:
Side 1= x
Side 2= x+20
Side 3= x+40
Side 4= x+60
Side 5= x+80
Total perimeter= 401
x+x+20+x+40+x+60+x+80= 401
Simplify it...
5x=201
x= 40.2
This is the answer= 40.2

Answer: 24%
Step-by-step explanation:
A company is expanding its building area from 16,500 square feet to 20,460 square feet. To calculate the percentage increase in the area of the building space, we first find the difference. This will be:
20,460 - 16,500 = 3960
We then divide the difference by the former building area and then multiply by 100. This will be:
3960/16500 × 100
= 0.24 × 100
= 24%
The percentage increase of the area of the building space is 24%.
