This also 7th fgrade homework!!
harkovskaia [24]

Answer:

Down the left-hand column, the pattern is counting by 5's. Therefore, 5, 10, 15, 20, 25. Down the right-hand column, the pattern is counting by 4's. Therefore, 4, 8, 12, 16, 20. Thus, the ratios are:

5:4

10:8

15:12

20:16

25:20

In other words, the first line (5:4) is the base ratio. The second line multiplies the original values by 2, the third line by 3, the fourth line by 4, and the fifth line by 5.

Answer:

The image below will explain the question

To figure out the length of portion BC, we will use the trigonometric ratio below

\begin{gathered} \sin\theta=\frac{opposite}{hypotenus} \\ oppsite=BC \\ hypotenus=8in \\ \theta=35 \end{gathered}

By substituting the values, we will have

\begin{gathered} \sin(\theta)=\frac{oppos\imaginaryI te}{hypotenus} \\ \sin35=\frac{BC}{8} \\ cross\text{ multiply, we will have} \\ BC=8\sin35 \end{gathered}

Hence,

The final answer is

\Rightarrow8\sin35^0

The FOURTH OPTION is the right answer
