Answer:
a = 24.7 ft
Step-by-step explanation:
We can use the Pythagorean theorem to solve this problem.
a^2 + b^2 = c^2 where a and b are the lengths and c is the hypotenuse
a = the unknown distance fro the building and b is the distance up the wall, and the hypotenuse is the length of the ladder
a^2 + 17^2 = 30^2
a^2 +289 = 900
Subtract 289 from each side
a^2 +289-289 = 900-289
a^2 =611
Take the square root of each side
sqrt(a^2) = sqrt(611)
a = 24.71841419
To the nearest tenth
a = 24.7 ft
Answer:
24.7 feet
Step-by-step explanation:
This is a Pythagorean theorem question
The ladder is the hypotenuse or c
the distance from the wall is a leg or a
and the wall is the other leg or b
a² + b² = c²
a² + 17² = 30²
a² + 289 = 900
-289 -289
b² = 611
√ √
b = √611
b = 24.7 feet

Answer:
y+7= -6/5(x+3)
Step-by-step explanation:
Point slope form for a line is given by
y-y1 = m(x-x1) where m is the slope and (x1, y1) is a point on the line
y - -7 = -6/5(x - -3)
y+7= -6/5(x+3)
So, x + y = 42 and y - x = 5;
Then, y = x + 5;
Finally, x + x + 5 = 42;
2x + 5 = 42;
2x = 37;
x = 18.5;
y = 18.5 + 5;
y = 23.5;
Answer:
