Answer:

See below

Step-by-step explanation:

-[-(11-22)]=-[-(-11)]=-[11]= \large\boxed{-11}

$ \left( \frac{3}{2} \right) \cdot \left(-\frac{22}{33} \right) = -\frac{66}{66}=\large\boxed{-1} $

$\frac{4^2}{5^2}=\large\boxed{\frac{16}{25}}  $

$-\frac{4}{3} -\frac{4}{13} =  -\frac{4 \cdot 13}{3 \cdot 13} -\frac{4 \cdot 3}{13 \cdot 3} = -\frac{52}{39} -\frac{12}{39} = \large\boxed{-\frac{64}{39}} $

$\sqrt{\frac{27}{3} } =\sqrt{9} =\large\boxed{3}$

HELP!!!!
Andrei [34K]

Answer: 90° , 60° and 30° .

Step-by-step explanation:

Given : In a right triangle with a leg of 4 units and a hypotenuse of 8 units.

One angle should be 90°. (A right triangle has a 90° angle.)

Let the given leg is the side opposite to the angle \theta  in the triangle.

Then by trigonometry , we have

\sin\theta=\dfrac{4}{8}=\dfrac{1}{2}  [Sine of an angle is the ration of the side opposite to the angle and the hypotenuse of a right triangle.]

Also , \sin 30^{\circ}=\dfrac{1}{2}

\Rightarrow\ \theta = 30^{\circ}

Let  x be the measure of the third angle.

BY Angle sum property of triangle , we have

90^{\circ}+30^{\circ}+x= 180^{\circ}\\\\ 120^{\circ}+x= 180^{\circ}\\\\ x=180^{\circ}-120^{\circ}\\\\ x= 60^{\circ}

Therefore , the measures of all angles in the triangle : 90° , 60° and 30° .
