Answer:

Exact value,  \angle B=\sin^{-1}(\frac{3}{4})

Approximation,  \angle B\approx 48.6^\circ

Step-by-step explanation:

In ΔABC, ∠C=90°

We are given a right angle triangle.

Side AB is hypotenuse = 4

Side AC is one leg = 3

Using trigonometry identity:

\sin\angle B=\dfrac{Perpendicular}{Hypotenuse}

\sin\angle B=\dfrac{AC}{AB}

\sin \angle B=\dfrac{3}{4}

\angle B=\sin^{-1}(\frac{3}{4})

\angle B=48.59^\circ\approx 48.6^\circ

The exact value of \angle B=\sin^{-1}(\frac{3}{4})

The approximation of \angle B\approx 48.6^\circ

Help pls my math teacher is rude​
Digiron [165]

Answer:

2.25 or 2 1/4 pounds

Step-by-step explanation:

if you add them all up (I converted them to decimals when adding) you get 13.5 or 13 1/2 if your using fractions, then you divide that by 6 because thats how many jars there are and you get 2.25 or 2 1/4

At a track meet, Tim ran at a constant speed of 300 meters per minute. After 8 minutes, he still had 600 meters left to run. The
gregori [183]
Okay so 300 meters per minute and he ran 8 minutes..

300x8=2400

He still had 600 left to go...

2400+600=3,000

He had to run three times longer than Eric...

3000/3=1000

Does that make sense?

-4(3 - 2x) + 2x = 2x - 8
Dennis_Churaev [7]

Answer:

C) x = ½

Step-by-step explanation:

Using the <em>Distributive Property</em> and combining like-terms will give you this:

-12 + 10x = 2x - 8

- 10x -10x

--------------------

-12 = -8x - 8

+ 8 +8

-------------

-4 = -8x [Divide by -8]

½ = x

American cars use about 600 000 000 gallons of oil per year. How many liters of oil do American cars use per year? Report your a
fiasKO [112]
<span>1 Liter = 1.05 quart. 1/1.05 Liter = 1.05/1.05 quart = 1 quart. Replacing this value of quart in the equation below. 1 gallon = 4 quarts 1 gallon = 4 * 1/1.05 Liters 1 gallon = 3.80952380952 Total oil consumption per year in gallons is 600,000,00 So, total oil consumption per year in liters is obtained by: 600,000,000 * 3.80952380952 = 2285714285.71 liters Converting to scientific notation, we have 2.28571 * 10^9 liters.</span>

Pls Help! John wants to prove ABC = to DEF. He Knoes AB = DE and AC = DF. With Screenshot
matrenka [14]

Answer:

\angle A \cong \angle D

Step-by-step explanation:

The Side-Angle-Side method cana only be used when information given shows that an included angle which is between two sides of a ∆, as well as the two sides of the ∆ are congruent to the included side and two sides of the other ∆.

Thus, since John already knows that \overline{AB} \cong \overline{DE} and \overline{AC} \cong \overline{DF}, therefore, an additional information showing that the angle between \overline{AB} and \overline{DE} in ∆ABC is congruent to the angle between \overline{AC} and \overline{DF} in ∆DEF.

For John to prove that ∆ABC is congruent to ∆DEF using the Side-Angle-Side method, the additional information needed would be \angle A \cong \angle D.

See attachment for the diagram that has been drawn with the necessary information needed for John to prove that ∆ABC is congruent to ∆DEF.
