sinE = \frac{3}{5}

the sine ratio is defined as

sin( angle ) = \frac{opposite}{hypotenuse}

here the opposite to ∠E is 6 and the hypotenuse is 10

sinE = \frac{6}{10} = \frac{3}{5}

S\frac{O}{H} C\frac{A}{H} T\frac{O}{A} or Sin\frac{Opposite}{Hypotenuse}Cos\frac{Adjacent}{Hypotenuse} Tan\frac{Opposite}{Adjacent}


At the point/angle E:

- the adjacent side(side <u>next to</u> the point/angle) is ED

- the opposite side(side of the triangle <u>across</u> from the point/angle) is DF

- the hypotenuse (the<u> longest side</u> of the triangle) is EF.


sin ∠E = \frac{opposite}{hypotenuse}

sin ∠E = \frac{6}{10} = \frac{3}{5} (simplified)

Krystal and Mary are selling fruit for a school fundraiser. Customers can buy small boxes of tangerines and large boxes of tange
irina1246 [14]

Using a system of equations, it is found that a small box of tangerines costs $10 and a large box costs $14.

<h3>What is a system of equations?</h3>
  • A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the <em>variables </em>are:

  • Variable x: Cost of a small box.
  • Variable y: Cost of a large box.

Krystal sold 7 small boxes of tangerines and 14 large boxes of tangerines for a total of $266, hence:

7x + 14y = 266

Simplifying by 7:

x + 2y = 38

x = 38 - 2y

Mary sold 14 small boxes of tangerines and 3 large boxes of tangerines for a total of $182, hence:

14x + 3y = 182

Since x = 38 - 2y:

14(38 - 2y) + 3y = 182

25y = 350

y = \frac{350}{25}

y = 14

Then

x = 38 - 2y = 38 - 2(14) = 10

A small box of tangerines costs $10 and a large box costs $14.

Two lines intersect to form four angles. The measure of one angle is 27 degrees. Draw a diagram to show the measures of the othe
Snowcat [4.5K]
Since there is a 180 degrees in a straight line and we know that the intersection of one angle is 27 degrees we can can say 180 -27 = 153 degrees.  So the four angles would be 27, 27 153, 153

A truck can at most be filled with 20 ton. If there are currently 14 ton goods there already, write an inequality representing t
Rom4ik [11]

Answer:

x + 14 \leq 20, x = 6 ton

Step-by-step explanation:

The truck can be filled with a total of 20 ton.

There are already 14 ton inside the truck, so if we call x the weight of goods that we can still add into the truck, we know that (x+14) must be equal at most at 20. Therefore, the inequality becomes:

x+14\leq 20

Solving it, we find

x\leq 6

which means that the most amount of goods that could be added to the truck is 6 tons.
