Gennadij [26K]

Answer:

18.4 feet

Step-by-step explanation:

-use the formula C^2 = A^2 + B^2 for a right triangle, which is made by the ladder and the wall.

-let the ladder be C, the wall be a, the base to the bottom be b.

-substitude into the equation, which will leave us with:

C^2 = 17^2 + 7^2

C^2 = 289 + 49

C^2 = 338

C = square root of 338, which is 18.4 feet!

nexus9112 [7]

Answer:

1. Exponent

2. Multiplication

3. Subtraction

4. Square root

5. Addition

6. Division?

<em>Note: I am not very sure about my answer because of two things. 1. The proper order for operating is PEDMAS (Parentheses, Exponent, Multiplication, division, addition, and subtraction). There is no Square root in that operation so I will consider it in the middle. 2. There is no division operation in this problem.</em>

Use the image below to answer the following question. Find the value of sin x® and cos yº What relationship do the ratios of sin
Flauer [41]

Answer:

sin(x) and cos(y) are equal and have ratio of 1 : 1

First find the missing hypotenuse using Pythagoras theorem:

a² + b² = c²

12² + 5² = c²

c = √144+25

c = 13

using sine rule:

sin(x) = \dfrac{opposite}{hypotenuse}

sin(x) = \dfrac{5}{13}

using cosine rule:

cos(y) = \dfrac{adjacent}{hypotenuse}

cos(y) = \dfrac{5}{13}
