Answer:
x= 90 degrees
y= 47 degrees
Step-by-step explanation:
Since the two sides of this triangle are equal in lengths, you know that it is an isosceles triangle.
So with this information, you know that the angle at the bottom left is also 47 degrees.
x would be equal to 90 degrees because it is perpendicular to the bottom of the triangle (assuming).
A triangle has 180 degrees, so add up the lengths we have to solve for the missing angle, y.
90+47+y=180
y= 43

Answer:
y=2x-5
Step-by-step explanation:
, and m=2
, -(-5)-Two negatives make it positive, and you distribute the 2
, you now subtract 5 to get y by itself to get your answer of
*NOTE* (0,-5) is the y-intercept, so you could have used the linear equation of y=mx+b, m=2, and b(y-intercept)=-5
giving you y=2x-5
Your answer would be C.
If you substitute 14 for X and add it to 9. You would get 23
Answer:
9 m/s
Step-by-step explanation:
To calculate the change in the tram's elevation each second, you must divide the given figures which is now the given formula of 
;
÷ 
Therefore, the change in the tram's elevation is 9 each second.
