Answer:
9.5 cm
Step-by-step explanation:
B ratio of angles ratio are 1:2:3
30-60-90 triangle (angles )
x-x√3 -2x triangle ( sides)
short side -long side- hypothenuse
2x = 19 so x= 19/2 = 9.5 cm
Answer:
<u>y = x ( - 3 ) + 1</u>
Step-by-step explanation:
Find what relationship x and y have. In this case, y is x multiplied by -3, plus 1.
(3,-8) The number 3 is x and -8 is y. Use the rule above to see if it's correct. Like so: -8 = 3 ( - 3) + 1
-8 = -9 + 1
-8 = -8
The rule/equation is correct.

130/2=65 miles per hour
30/2=15
Answer:
Sin(theta) = 3/5
Step-by-step explanation:
Remark
The Sin(theta) = opposite / hypotenuse
The opposite side is not defining the angle. The hypotenuse is the longest side of a right triangle.
In this case the opposite is 3
The hypotenuse = 5
Answer: Sin(theta) = 3/5
