Answer:
Step-by-step explanation:
Alright, lets get started.
1.
[tex]cos 64=\frac{y}{8}[/tex]
[tex]y=8cos64 = 8*0.4383711=3.50[/tex]
S,the answer is 3.5 (B) : Answer
7.
Please refer the diagram I have attached.
Using SOH CAH TOA
[tex]tan (angle)=\frac{opposite}{adjacent}[/tex]
[tex]tan(angle)=\frac{17}{14}[/tex]
[tex]angle=tan^{-1}(\frac{17}{14})[/tex]
angle = 50.5
Hence angle is whole degree is 51. (A): Answer
8.
distance between two point is :
[tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
[tex]\sqrt{(-3-7)^2+(3+7)^2}=\sqrt{100+100}[/tex]
[tex]\sqrt{200}[/tex]
14.14
So, the answer is 14 (A) : Answer
9.
Distance between two points is :
[tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
[tex]\sqrt{(-9-7)^2+(5+6)^2}=\sqrt{256+121}[/tex]
[tex]\sqrt{377}[/tex]
19.4
So the answer is 19 : Answer (D)
Hope it will help :)
