Answer:
A.) ![f(x)=25x+40](https://tex.z-dn.net/?f=f%28x%29%3D25x%2B40)
Step-by-step explanation:
Answer:
x =10
y = 10 sqrt(3)/ 3
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 60 = 5 sqrt(3) / x
x sin 60 = 5 sqrt(3)
x = 5 sqrt(3)/sin 60
x = 5 sqrt(3) / sqrt(3)/2
x = 5*2
x =10
tan theta = opp /adj
tan 60 = x/y
ytan 60 = 10
y = x/ tan 60
y = 10/ sqrt(3)
y = 10/ sqrt(3) * sqrt(3)/ sqrt(3)
y = 10 sqrt(3)/ 3
Answer:
y = 8x - 11
Step-by-step explanation:
Using the equation
<u>y - y1 = m (x - x1)</u>
<u>y - 5 = 8 (x- 2)</u>
<u>y - 5 = 8x - 16</u>
Subtract the 5
y = 8x - 11
Answer:
angle 8= 120 degrees
angle 7= 60 degress
Step-by-step explanation:
So since it's a line, they will equal 180. So since angle 7 is half of 8 we need to a pair of numbers that add to 180. So you can find out that 120/2 is 60. Then 60+120=180
