You weigh a gallon of 2% milk in science class and learn that is approximately 8.4 pounds. You pass the milk to the next group,
iris [78.8K]
1 pound is 0.453592 kilograms
so 8.4 pounds is 3.81018 kilograms
You would cross multiply and make sure the units are lined up with each other

1\frac{1 lb}{0.453592 kg}  =  \frac{8.4 lb}{x}
then you would cross multiply and get 3.81018

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° .
