Answer:
90°
Step-by-step explanation:
It looks slightly obvious, but here's the complicated explanation.
Converse of the Consecutive Interior Angles Theorem. Solve.
x+96+x+96=180
Simplify.
2x+192=180
Subtraction Property of Equality (subtract 192 from both sides to isolate 2x).
2x=-12
Division Property of Equality (divide both sides by 2 to isolate x).
x=-6
Now that you have your x value, plug it in into your bolded equation.
x+96
-6+96
Simplify.
90°
5x - 20y = 60...reduce by dividing by 5
x - 4y = 12
this is the same as the other equation....therefore, it is the same line...meaning infinite solutions
=============
y - 7x = -14
y = 7x - 14.....slope = 7, y int = -14
7y - 49x = -2
7y = 49x - 2
y = 7x - 2/7.....slope is 7, y int is -2/7
if the slopes are the same, but the y int are different, then u have a parallel lines with no solutions
Answer:
No. The ladder is too steep.
Step-by-step explanation:
Length of ladder = 17 feet. This is the hypotenuse.
Side a of a right triangle = 16.6
To answer this, you need one of the trigonometric functions.
Opposite = 16.5
hypotenuse = 17
The function you need is the sine function.
Sin(theta) = opposite / hypotenuse
sin(theta) = 16.5 / 17
Sin(theta) = 0.97059
theta = sin-1(0.07059)
theta = 76.07
No the ladder is too steep.
