Step-by-step explanation:
Third angle = 180° - (70° + 55°)= 180° - 125° =55°
Since, all the angles of triangle are acute angles, hence it is a acute angled triangle or scalene triangle.
The correct answer is 231/1000
Answer:
20°
Step-by-step explanation:
In circle with center O, PS is diameter.
(angle inscribed in semicircle)
PQRS is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
If d = rt, Then r = d/t
avg speed = 720/t
Therefore after subtracting penalty points, the function for score is:
For part 2 i will attach a picture.
Part 3)
Set s = 3 and solve for t
