Tan (angle B) using an exact expression in trigonometric ratios in right triangles

1 answer:

4 0

The value of the tangent of an angle is the ratio (opposite side) / (adjacent side).

Here you see that the opposite side (opposite to Angle B) is of length 5 and the adj. side has length 12.

Thus, the tan of Angle B is 5/12. (answer)

X/6 + 2x/3 = 5 what is the value of x in the equation

ycow [4]

The value of x is 6 in the equation.

Step-by-step explanation:

Given equation is;

$\frac{x}{6}+\frac{2x}{3}=5$

Taking least common multiple

$\frac{x+4x}{6}=5$

Multiplying both sides by 6

$6*\frac{5x}{6}=5*6\\5x=30$

Dividing both sides by 5

$\frac{5x}{5}=\frac{30}{5}\\x=6$

The value of x is 6 in the equation.

Find all solutions of the equation x^2 -2 x + 6 = 0 by completing the square. Express the soutions in the form a + b i:

Leto [7]

$x^2-2x+6=0\\
x^2-2x+1+5=0\\
(x-1)^2=-5\\
x-1=\sqrt{-5} \vee x-1=-\sqrt{-5}\\
x=1+5i \vee x=1-5i\\$
