Answer:

X = 105

Step-by-step explanation:

<u>2x</u> = 42

5

Multiply both sides by 5

5 × <u>2x</u> = 5×42

5

5 cancle 5

2x = 5 × 42

2x = 210

Divide both sides by 2

<u>2x</u> = <u>210</u>

2 2

x = 105

Find sin A for the triangle below. Give the exact value as an expression and an approximation to the nearest ten-thousandth. Not
Feliz [49]

the exact value of sin A  to the nearest ten- thousandth is 0. 6625

<h3>Using the pythagorean theorem</h3>

a² + b² = c²

The opposite side is unknown, so use the pythagorean theorem to find it

c = hypotenuse = 4

a= opposite site = ?

b= adjacent side = 3

Substitute into the formula

4² = a² + 3²

16 = a² + 9

a² = 16 -9 = 7

Find the square root

a =√7 = 2. 65

To find Sin A, use

Sin A = opposite side ÷ hypotenuse

Sin A = 2. 65 ÷ 4 = 0. 6625

Thus,  the value of sin A is 0. 6625

In 5 OR MORE SENTENCES, write a short story explaining the graph OR write about the key features of the graph.
rewona [7]

The graph illustrated is divided into three seperate sections namely <em>A, B and C,</em> the short story culled from the graph is described thus:

Rate of change or slope = (Rise/ Run)

  • <em>Rise = y2 - y1 </em>
  • <em>Run = x2 - x1 </em>

<u>SECTION A:</u><u> </u>

Slope = (40 - 0) ÷ (20 - 0) = 40/20 = 2

Distance traveled = 50 meters

<u>SECTION B</u> :

This section gives an horizontal line, hence, the slope is 0.

Distance covered = 0 ; as there was no change in the distance over the period of time.

<u>SECTION</u><u> </u><u>C</u><u>:</u>

Slope = (80 - 50) ÷ (70 - 60) = 30/10 = 3

The total distance traveled = 80 - 50 = 30 meters

<u>The total </u><u>distance</u><u> </u><u>and</u><u> </u><u>time spent traveling</u> :

Total distance traveled = (50 + 30) = 80 meters

Total time spent = 70 seconds (<em>time at the 80 meter mark</em>)

Hence, the story.
