Answer: (x - 1)(8x +5)
Step-by-step explanation:
Answer:
∠1=160° and ∠2=20°
Step-by-step explanation:
Let ∠1 = x
∠2 = y
as these two angles are supplementary their sum is 180
that x+y=180 ----(A)
Also given that ∠1 is 20 degree less than nine times the size of ∠2.
Hence
x=9y-20
putting value of x in A and solving for y
9y-20+y=180
10y=180+20
10y=200
y=10
Putting this y in A
x+10=180
x=160
If you would like to solve 7% of what length is 200 ft, you can calculate this using the following steps:
7% of what length is 200 ft
7% * x = 200
7/100 * x = 200 /*100/7
x = 200 * 100 / 7
x = 2857 ft
Result: 7% of 2857 ft is 200 ft.
4x = 32 - 2x
Add -2x (or subtract 2x) from each side
2x = 32
Divide both sides by 2
x = 16
