All of the angles in a triangle equal 180° so if the first 2 angles are 60°, combined that equal 120°, leaving 60° left. X= 60°
Answer:
(X+2)power of 2 + (y + 3)power of 2 = 9

Step-by-step explanation:
We have, Sorin hits a cricket ball straight up into the air. After 1.5 s, the ball is falling straight down with a speed of 6.5 m/s.
We want to find the initial vertical velocity of the ball.
The relation between initial speed, final speed, acceleration and time is given by using first equation of kinematics. Let v₀ is the initial speed. So,

Here, v = -6.5 m/s, t = 1.5 s and a = -g

So, the initial velocity of the ball is 8.2 m/s and the formula used is (1).
