Answer:
<u><em>angle bac</em></u><u><em> is the answer</em></u>
Step-by-step explanation:
both rays emanate from the shared point 'a', which will be the vertex of angle bac
Answer:
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) (2, −2)---------> this point belong to the IV quadrant
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°)
mark me branlest plz hope it helps
Answer:
x= 67 degrees and z= 54 degrees
Step-by-step explanation:
Using alternative interior angle, you can see that x is equal to 67 degrees
-In a triangle, there is 180 degrees. Since there are 59 degrees and 67 degrees in the triangle, you will just need to solve for z.
-In order to solve for z, you subtract 180-59-67= 54
Hope this helps!
Answer:
Step-by-step explanation:
<u><em>Given that:</em></u>
R is a point lying on line TS
So,
TS = TR + RS
Where TR = 4.5 and RS = 6
=> TS = 4.5 + 6
=> TS = 10.5
It would be 4.05 because the 1 is lower so it is rounded down
