Answer:
y = 38°
x = 89°
Step-by-step explanation:
- y = 38°
( because y and 38° are pair of alternate interior angle )
2. x + 53° + 38° = 180°
( because sum of all interior angles of the triangle is 180° )
- x + 91° = 180°
- x = 180° - 91°
- x = 89°
The equation:

has the form:
y = mx + b
with

m is known as the slope of the line, then the slope is -2/3
4/11 is equivalent to the fraction 0.363636.... I got this answer by dividing the 4 in 11 groups, or doing the equation, 4<span>÷11</span>
Answer:
1 seconds after being thrown, the stone reaches its max height
Step-by-step explanation:
The parabolic (quadratic) equation is:

Lets expand this in the form
, so we have:

We can say the values of a,b, and c, now to be:
a = -5
b = 10
c = 40
The number of seconds at which the max would occur is given by the point, x, at:

We know a and b, let's find the seconds, x,

Hence,
1 seconds after being thrown, the stone reach its max height
Answer:
A)6
B)ST
Step-by-step explanation:
A if u turn it, 15 is equal to the 10
15/9=10/x
x=90/15
x=6
B) Turn it so #2 is facing up.
ST is the same.
Hope this helps plz hit the crown :D
