Answer:
Step-by-step explanation:
We have the conversion from polar coordinates to cartesian as
x =rcost and y = rsint where (r,t) are the polar coordinates
Also all trignometric functions are periodic with period = 2pi
Using this we find out

Thus we converted polar to rectangular coordinates.
Reverse would be
from (x,y) to (r,t) as

Answer:
10a: △ABC is an Equilateral triangle with all acute angles.
10b: △BCD is A scalene triangle with all acute angles.
10c: △BDE is An Isosceles triangle with one obtuse angle.
Step-by-step explanation:
10) Looking at the diagram at the bottom left;
- △ABC has 3 equal internal angles and as such, it means it will have 3 equal angles.
Thus, we can classify it as; Equilateral triangle with all acute angles.
- △BCD has 3 unequal angles. Thus, it's 3 sides are not equal. Also all the angles are less than 90°.
We can classify it as;
A scalene triangle with all acute angles
- △BDE has 2 equal angles and one angle greater than 90°. This means it has 2 equal sides.
Thus, we can classify it as;
- An Isosceles triangle with one obtuse angle.
594 7/25 converted into decimal is 594.28, 89 37/100 converts to 89.37. Add 594.28 and 89.37 together and we get out final answer of 683.65. Convert that back into fraction form and we get (683 13/20) <--- Final Answer
