Answer:
29
Step-by-step explanation:
if it is a right triangle, one of the angles are already 90 degrees. by giving me another angle, 61, all I have to do is add the 61 and 90 then subtract it from 180. A triangle is half of a square, a squares angles add together to make 360 degrees. a triangle is half of a square, so the angles add up to 180. that is why we subtract 151 from 180. doing that gives us the answer of 29. the third angle must be 29 degrees
Answer:
Depth = 7.06 m
Velocity = 11.77 ms-1
Step-by-step explanation:
We use the equation of motion:-
s = ut + 1/2 g
where s = distance fallen , t = time , u = initial velocity and g = 9.81 ms^-2 , the acceleration due to gravity.
So s = 0(t) + 1/2 * 9.81 (1.2)^2
= 7.06 m to nearest tenth.
We use another equation of motion to find the final velocity:-
v^2 = u^2 + 2gs where v = final velocity
v^2 = 0 + 2*9.81 * 7.06
= 138.52
v = √138.52 = 11.77 m s-1
AB = 3, BC = 4, AC = 5 because of a 3-4-5 right triangle.
Perimeter = 12 for both triangles.
The answer is 2,500. You must multiply both of the equations and add them together. The answer will be 2500.
6, 2
because 6 is 3 times the amount of 2.
