So... You have to solve for y, graph it, and then find where the lines intersect.You can take a table and put in all the x and y valuesThen graph it.. And see where it intersectsBecause usually these equations are lines

<u>Answer-</u>
<em>At 15.91° the ball was thrown.</em>
<u>Solution-</u>
<em>In the question it is given that the ball was released and caught from the same height.</em>
We know that,

Where,
R = Range of the projectile = 7.75 m,
u = Initial speed = 12 m/s
θ = Angle at which it was released
g = Acceleration due to gravity = 9.8 m/s²
Putting all the values,





Answer:
<BAC = 20°
Step-by-step explanation:
It is given in the question that all 9 triangle which are formed are congruent, which means that in all triangles, the angle which is formed at point A is same.
Which means 9 angles collectively can be written as 9 · <BAC
If we consider all the 9 triangles, we can see in the figure that it forms a semicircle.
A semicircle has a total sum of angles equal to 180°
So we can write that:
9 · <BAC = 180°
Simplify for <BAC
<BAC = 20°
