5tanx-2cotx+1=0...... .
Verdich [7]

Step-by-step explanation:

5(tanx)^2 -2 +tanx=0

let tanx=y

5y^2 + y-2=0

y=0.5403 or y= -0.7403

tanx=0.5403

x=arctan(0.5403)

x=28.38°

or

tanx=-0.7403

x=arctan(-0.7403)

x=143.49°

Answer the following question. (need to show work) 20/2-10+3*15=
slava [35]

Answer:

45.

Step-by-step explanation:

To solve this equation, we must use PEMDAS...

The operations listed first must be solved first before we can continue.

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

Using this, we find that we must complete the multiplication and division before we add or subtract.

20 / 2 - 10 + 3 * 15

= (20 / 2) - 10 + (3 * 15)

= 10 - 10 + 45

= 0 + 45

= 45

Hope this helps!
