Answer:
SAS
Step-by-step explanation:
the correct answer is side angle side (SAS)
The simplest from of 3/12 is 1/4.
3/12 divide 3 by 3 and 12 by 3 an you get 1/4
We know that
the relationship between the 2-dimensional polar and Cartesian coordinates is
r = √(x² + y²)
Θ = tan⁻¹ (y/x)
so
Part a) <span>(2, −2)---------> this point belong to the IV quadrant
</span>r = √(x² + y²)------ r = √(2² + (-2)²)-----> r=√8
Θ = tan⁻¹ (y/x)---- Θ = tan⁻¹ (2/2)----> 45°
remember that the point belong to the IV quadrant
so
Θ=360-45-----> Θ=315°
the answer part A) is
(r,Θ)=(√8,315°)
Part b) (-1, 3)---------> this point belong to the II quadrant
r = √(x² + y²)------ r = √(-1² + (3)²)-----> r=√10
Θ = tan⁻¹ (y/x)---- Θ = tan⁻¹ (3/1)----> 71.57°
remember that the point belong to the II quadrant
so
Θ=180-71.57-----> Θ=108.43°
the answer part B) is
(r,Θ)=(√10,108.43°)
I think that it is around 47 degrees.
Answer:
Step-by-step explanation:
hello :
f(x) = 3x - 5 and g(x) = x² + 2
(f+ g)(x)= f(x)+g(x) = 3x-5 +x²+2
(f+ g)(x).= x²+3x-3
