Answer:
6
Step-by-step explanation:
Because they give you a 60 degree angle and a right angle, we know this is a 30 60 90 triangle. Because of the properties of a 30 60 90 triangle, we know that if the shortest side (the bottom) is referred to as b, the hypotenuse will be 2 times the value of b (2b) and the side x would be b times the square root of 3. To solve this you would divide 12 by 2 to get b, which would be 6. To get the side you're solving for, x, you would then multiply 6 by the square root of 3. this is your answer.

Given problem;
We are to make t, the subject of the expression v = u + at.
The equation is one of the equations of motion.
Usually, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
To make "t" the subject of the expression; follow these steps;
v = u + at
- Subtract "u" from both sides;
v (-u) = u (-u) + at
2. the expression is now;
v - u = at
3. now multiply both sides by to isolate "t";
(v - u) = at x
t =
