Answer:
because we cant help you here can you drop a screenshot in so then we can help because all we know is find the value of x and y and if we had a screenshot then we would know what we are trying to calculate here
Step-by-step explanation:
Answer:
12 ft
Step-by-step explanation:
The ladder forms a right triangle with the building and the ground, since the ground is perpendicular to the building
Therefore, we can use the Pythagorean theorem:
c2 = a2 + b2
From the information in the problem, c is 20 ft, b is 16 ft, and a is what we solve for:
(20 ft)2 = a2 + (16 ft)2
a = √((20 ft)2 - (16 ft)2) = 12 ft
First solve for the slope, m using the two points given. It doesn't matter which point you choose as point 1 or 2 as long as you're consistent.
m = (y2 - y1)/(x2 - x1)
point 1: (–6.4, –2.6)
point 2: (5.2, 9)
m = (9 - -2.6)/(5.2 - -6.4)
m = (9 + 2.6)/(5.2 + 6.4)
m = 11.6/11.6
m = 1
put the newly found slope into the linear equation for m
y = (1)x + b
y = x + b
Now solve for the y-intercept, b
by putting one of the given points
9 = 5.2 + b
b = 9 - 5.2
b = 3.8
final equation:
y = x + 3.8
Answer:
Step-by-step explanation:
we know that
Applying the <u>Intersecting Secants Theorem</u>
Solve for x
1/3 of 12. This is because if you divide 12 by three, then you get a greater number than when you divide 12 by four.
