To solve a quadratic equation 
we can use the quadratic formula:
In your case, the equation is identified by 
So, the solving formula yields
So, the two solutions are derived by choosing the plus sign once, and the minus sign the other time:
Step-by-step explanation:
tan x = 3/4
Tangent is opposite over adjacent, so draw a right triangle with angle x where the opposite side is 3 and the adjacent side is 4.
Use Pythagorean theorem to find the hypotenuse:
c² = 3² + 4²
c² = 25
c = 5
Sine is opposite over hypotenuse, so:
sin x = 3/5

5x6= 30 (divided by 2= 15)
5x6=30 (divided by 2 = 15)
10x18= 180
180+30= 210

Answer:
cot(-270) = 0
Step-by-step explanation:
given cot ( -270)
In trigonometry function we will use cot ( -x) = -cotx
so cot (-270) = - cot270
<u>trigonometry table</u>
II quadrant I quadrant ( All positive)
sin θ 90+θ 90 -θ
<u> cosec</u> θ <u> 180-θ 360+θ</u>
third quadrant fourth quadrant
tan θ 180+θ cos θ 270+θ
cot θ 270 - θ sec θ 360-θ
Given
cot (-270) = -cot ( 270)
= - cot ( 180 + 90) (third quadrant above table)
= -cot 90 =0 ( cot θ positive in third quadrant
<u>Final answer</u>:-
cot(-270) =0
