An 18-foot ladder is leaning against a vertical brick wall. The base of the ladder is 9 feet away from the wall.

Triss [41]

A^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 + 81 = 324
a^2 = 243
a = 15.589 = 15.6 feet is the angle the ladder is at :)

PLEASE HELP ASAP!!!! I GIVE A BRAINLIEST TO THE RIGHT ANSWER!!!!

Mandarinka [93]

Use cosine law to solve the problem. See image attached.
What we're looking for is the length of side A (a side which is opposite with angle A).

This is the formula of cosine law
A² = B² + C² - 2BC cos A

Input the numbers
A² = 75² + 90² - 2(75)(90) cos 85°
A = $\sqrt{75^{2}+90^{2}-2(75)(90)cos85^{0}}$
A = $\sqrt{90^{2}+75^{2}-2(90)(75)cos85^{0}}$

What is the equation of the line that passes through the point (4, -4) and has a<br> slope of –3/4?

Gelneren [198K]

Answer:

y=-3/4x-1

Step-by-step explanation:

y=mx+b; y is the y coordinate; m is the slope; x is the x coordinate; you have to find b. So you replace all the numbers out which is given to you;

-4=-3/4(4)+b (you multiply -3/4 by 4 and get -3)

-4=-3+b (you add 3 to both sides and get -1)

-1=b (you now found b so plug it into the equation)

y=-3/4x-1
