HA stands for Hypotenuse Angle theorem.
This is a special case of b. AAS theorem
This is because you would be given a side length ( hypotenuse and an acute angle). and since we would already know that a right triangle has a right angle, so we would have 2 angles and a side = AAS.
The velocity is 4. You didn’t say what you needed to find but I’m pretty sure it’s that
Answer:
21 s t^2
Step-by-step explanation:
7t · s · 3rt
Multiply the coefficients
7*3 =21
t*t = t^2
s
Multiply back together
21 s t^2
