Answer:
x = -5
Step-by-step explanation:
x + 115 = 110, they are acute to each other
∴ x = 110 - 115
x = -5
Answer:
10.6 ft
Step-by-step explanation:
to find the diagonal length of the stairway we can use the pythagorean theorem or a^2 + b^2 = c^2
6'4" is also 6 1/3' or 19/3'
8'6" is also 8 1/2' or 17/2'
now square them both
361/9 + 289/4
make them have the same denominator
1444/36 + 2601/36
add them
4045/36
take the square root
10.6000524 is your answer
10.6 ft
Slope = change in y / change in x
= (15 - 9) / (7 - 5)
= 6 / 2
= 3
Answer:
The answer is 675.75
Step-by-step explanation:
159 × 4.25= 675.75
well i cannot help u graph but u need to get them in y=mx+b form first
2x+y=4
y=-2x+4
2y-4x=6
2y=4x+6
y=2x+3
now that the problems are in y=mx+b form, u can graph them. the "b" is your y-intercept. you need to graph this first so what ever ur be is, put a point there on the y axis. then use your slope to plant your line. slope is rise/run. so for the top problem start at your y intercept and go down 2 and to the right 1. and for the bottem problem, start at your y intercept then go up 2 and to the right 1
HOPE THIS HELPED!
