Step-by-step explanation:
The equation used to find the equation for a line with two intercepts is called point slope form. , where
and
are the intercept points and m is the slope.
However, we need the slope to use this formula.
Use
m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}
y - ( -7 ) = m ( x - ( 4 ) )
y - ( -7 ) = -7/4 ( x - ( 4 ) )
y + 7 = -7/4 ( x + 4 )
y + 7 =
y + 7 =
y + 7 =
y + 7 = - 7
y =
Answer:
(A) 2 meter
Step-by-step explanation:
It is given that the ladder forms a 72º angle with the ground and rests against the house at a spot that is 6 meters high.
Let the measure of bottom of the ladder from the wall be x, then using the trigonometry, we have
≈
Thus, option A is correct.
