Transform each polar equation to an equation in rectangular coordinates and identify its shape. a. 1.34 radians

b. r = tan theta sec theta

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.

The answer is 3hope it : )

The hypotenuse in a right triangle is the longest side.to explain whether a triangle is a right triangle, we have to apply pythagoras: 13² = 12² + 5²169 = 144 + 25169 = 169, then this triangle is a right triangle
