1. Explain and find the length of segment AB. 2. Explain how to find the mÐA and find the measure rounded to the nearest degree.

3. Write the ratios of sinA and cosB. Explain the relationship between sinA and the cosB.

sinA = _ cosB = _

4. A 40-foot ladder is leaning against a building and it makes 50° with the ground. How far up the wall does the ladder reach? Be sure to draw a picture that describes this scenario, round your answer to the nearest tenth.

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

the answer would be  

a.

3: 1

step-by-step explanation:

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
