To wash a window that is 12 feet off the ground, Wayne leans a 13-foot ladder against the
AlladinOne [14]

Answer:

5 meters

Step-by-step explanation:

Based on the situation, it forms into a right triangle. So we will apply the Pythagorean Theorem here. The ladder acts as the hypotenuse while the height from the ground to the window serves as our side "a". We are tasked to solve for "b". Side "b" is the distance from foot of side a to the tip of side c which is the hypotenuse (ladder). We will derive the formula below to solve for b.

c = √( a² + b² )

c² = a² + b²

b² = c² - a²

b = √ ( c² - a² )

b = √ ( 13² - 12² )

b = 5 meters

Correct me if I'm wrong. I hope it helps.

How to estimate 9.1% of 59.3
gavmur [86]

Answer:

6

Step-by-step explanation:

For a quick rough estimate, I'd round 9.1% up to 10% and 59.3 to 60.  10% of 60 is 0.1(60) = 6.

For a more accurate estimate, round 9.1% down to 9% and 59.3 up to 60.  Then 9% of 60 is 5.4.

Help triangle sum therom and idk what to do
m_a_m_a [10]
Your answer would be x = 12

The triangle sum theorem states that the 3 angles in a triangle equal 180.

Since we have a 90 degree angle shown, we can add it to the other two and set it equal to 180.

30+90+6x-12=180
108+6x=180
6x=72
x=12

Answer:

C.)      Triangle TUV ~ Triangle WXY

Step-by-step explanation:

Find  the angles that are equal in each triangle, and put them in the same position in the statement.

T and W are equal; therefore, they are first in each.

U and X are equal; therefore, they are second in each.

V and Y are equal; therfore, they are last in each.
