If Cos A >0, and Csc A < 0, what quadrant does A lie?

Mathematics

Answer:

Quadrant IV.

Step-by-step explanation:

You need to remember that :

All trig ratios are positive in the Quadrant I.

Sine and csc are positive in Quadrant II.

Tan and cot are positive in Quadrant III.

Cos and sec are positive in Quadrant IV.

So if cos A > 0 ( ie positive) it is in either Quadrant I or IV.

Csc is <0 (negative) so it is in either Quadrant II or IV.

So if cos A > 0 and csc < 0 , A must be in Quadrant IV.

Hope this helps.

Feel free to ask questions if this is not entirely clear.

angle and angle b are complentary angles. if angle a = (2x-5) and m angle b = (5x+4) then find the measure of angle a
iris [78.8K]

complementary angles = 90

2x-5 + 5x+4 = 90

combine like terms

7x-1 =90

7x = 91

divide by 7

x =13

angle a

2x-5

2*13-5

26-5

21

Angle a: 21

2x+6=3x+4 Write a real-world problem that can be represented by the given equation. Explain what your variable represents.
Slav-nsk [51]

Here, we are required to write a real-world problem that can be represented by the given equation

On the left hand side of the equation, we can say that :

The addition of 6 to twice my cousin's age which gives 2x+6.

On the right hand side, we can say the addition of 4 to thrice my cousin's age which also gives:

3x +4

Ultimately, the real-world problem may be in the form :

Six added to Twice my cousin's age is equal to 4 added to thrice his age.

Also, my variable, x represents my cousin's age.
