The correct answer is option B which is $SinA = \dfrac{4}{5}$ , $tanA = \dfrac{4}{3}$ , $SecA=\dfrac{5}{3}$ ,

$CosA=\dfrac{3}{5}$ , $CotA=\dfrac{3}{4}$ and $CscA=\dfrac{5}{4}$ .

<h3>What is trigonometry?</h3>

Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.

From the figure we can see that two sides are Ab = 15 cm and BC = 12 cm third side will be calculated by pythagorean theorem.

AC² = AB² - BC²

AC² = 15² - 12²

AC² = 81

AC = √81

AC = 9 cm

Now all the trigonometry identities are:-

$SinA =\dfrac{BC}{AB}=\dfrac{12}{15}= \dfrac{4}{5}$ ,

$tanA =\dfrac{BC}{AC}=\dfrac{12}{9}= \dfrac{4}{3}$ ,

$SecA=\dfrac{AB}{AC}=\dfrac{15}{9}= \dfrac{5}{3}$ ,

$CosA=\dfrac{AC}{AB}=\dfrac{9}{15}= \dfrac{3}{5}$ ,

$CotA=\dfrac{AC}{BC}=\dfrac{9}{12}=}\dfrac{3}{4}$

$CscA=\dfrac{AB}{BC}=\dfrac{15}{12}= \dfrac{5}{4}$ .

Therefore correct answer is option B which is $SinA = \dfrac{4}{5}$ , $tanA = \dfrac{4}{3}$ , $SecA=\dfrac{5}{3}$ , $CosA=\dfrac{3}{5}$ , $CotA=\dfrac{3}{4}$ and $CscA=\dfrac{5}{4}$ .

The perimeter of a rectangle with a length of 10 units which equation can be used to find the width of the rectangle

sergeinik [125]

Answer:

2w + 20 = 55

Step-by-step explanation:

Here is the full question

The perimeter of a rectangle with a length of 10 units is 55 units. Which equation can be used to find the width, w, of the rectangle?

w + 10 = 55

w + 20 = 55

2w + 10 = 55

2w + 20 = 55

The perimeter of a rectangle's formula is = 2 ( length + breadth)

from the question ,

perimeter is 55 and length is 10

2(10 + w) = 55

20 + 2w = 55

Jessica ran on the track team at her school. She finished the 200-meter race in 54 seconds. What was jessica's average speed,in

Scrat [10]

Answer:

$v =\frac{x}{t}$

Where x represent the distance and t the time if we replace the info given we got:

$v = \frac{200m}{54 s} =3.704 \frac{m}{s}$

Then the average speed for this case in m/s is 3.704 for the 200 meter race

Step-by-step explanation:

The problem provides for this case the amount of distance travelled by Jessica in a given time. And we know that travels 200m in 54 seconds.

We want to find the average speed and we can use the following formula:

$v =\frac{x}{t}$

Where x represent the distance and t the time if we replace the info given we got:

$v = \frac{200m}{54 s} =3.704 \frac{m}{s}$

Then the average speed for this case in m/s is 3.704 for the 200 meter race
