Answer:
17.3
Step-by-step explanation:
sin(30)=0.5
0.5*20=100

x=17.3
I think you basically just got to add everything up . I mean , i can already tell this is a graph question but it says perimeter so perimeter somehow means add everything up. But im still not too sure ..
Answer:
14
Step-by-step explanation:
How many 1/2s are in 7? Then, write a multiplication equation and a division equation that answer the question.
Let the number of 1/2s = x
Hence:
Division Equation =
7 ÷ 1/2
Multiplication Equation =
= 7 × 2/1
= 14
There are 14 1/2s in 7
ANSWER
![B.\text{ }18](https://tex.z-dn.net/?f=B.%5Ctext%7B%20%7D18)
EXPLANATION
Let us make a sketch of the square:
Each angle in a square is equal to 90 degrees. This implies that:
![5x=90](https://tex.z-dn.net/?f=5x%3D90)
Solve for x by dividing both sides of the equation by 5:
![\begin{gathered} \frac{5x}{5}=\frac{90}{5} \\ \\ x=18 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B5x%7D%7B5%7D%3D%5Cfrac%7B90%7D%7B5%7D%20%5C%5C%20%20%5C%5C%20x%3D18%20%5Cend%7Bgathered%7D)
The answer is option B.
