dolphi86 [110]

1)
multiply all by the least common multiply:

$(\frac{1}{2} ) \times 4 = 2$

$( - \frac{3}{4} ) \times 4 = - 3$

$( \frac{1}{4} ) \times 4 = 1$
$+ 1z = - 3$
$z = \frac{ - 3}{1}$
$z = - 3$

AC, BD and EDC are straight lines.

11Alexandr11 [23.1K]

X=62
Vertically opposite angles are equal

Y=44
Angles on a straight line add up to 180

Z =286
Because
180-x-y=74
360-74=286

Simplify this expression: cos theta/ tan theta cot theta

Dmitry_Shevchenko [17]

Q: $\frac{cos\theta}{tan\theta.cot\theta}=?$

A:

$\frac{cos\theta}{tan\theta.cot\theta}=cos\theta$

because... $tan\theta.cot\theta=1$
*********************************************************
Q: $\frac{cos\theta}{tan\theta}.cot\theta=?$

A:

$\frac{cos\theta}{tan\theta}.cot\theta&= \\ \\ \frac{cos\theta}{\frac{sin\theta}{cos\theta}}.\frac{cos\theta}{sin\theta}&= \\ \\ \frac{cos^2\theta}{sin\theta}}.\frac{cos\theta}{sin\theta}&= \\ \\ \frac{cos^3\theta}{sin^2\theta}}&= cos^3\theta.cosec^2\theta$
