Which of the following is true about the right triangle?

katrin2010 [14]

Option 1. $cos (a) = \frac{3}{5}$ , option 3. $sin (a) = \frac{4}{5}$ , and option 5. $tan (a) = \frac{4}{3}$ are true about the right triangle.

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Here the hypotenuse measures 15 units. Assume the other side measures x.

$15^{2} = x^{2} +9^{2} , x^{2} = 15^{2} -9^{2} .$

$x^{2} = 144, x= 12.$

Step 2:

$sin \theta = \frac{oppositeside}{hypotenuse} ,cos \theta = \frac{adjacentside}{hypotenuse} , tan \theta = \frac{oppositeside}{adjacentside}.$

For angle A, the opposite side is 12 units long, the adjacent side is 9 units long and the hypotenuse is 15 units long.

$sin (a) = \frac{12}{15} ,cos(a) = \frac{9}{15} , tan(a) = \frac{12}{9}.$

$sin (a) = \frac{4}{5} ,cos (a) = \frac{3}{5} , tan (a) = \frac{4}{3}.$

So option 1. $cos (a) = \frac{3}{5}$ , option 3. $sin (a) = \frac{4}{5}$ , and option 5. $tan (a) = \frac{4}{3}$ are true about the right triangle.

Sixty-four percent of the students correctly described the process of photosynthesis. If 63 students did not correctly describe

olganol [36]

Answer:

Number of students who correctly describe the process = 112 students.

Step-by-step explanation:

From the information provided in the question;

64% correctly described the process of photosynthesis.

63 students didn't describe correctly the process of photosynthesis.

We are to find the number of students that did correctly describe the process of photosynthesis.

First of all we need to find the total number of students.Lets represent this value to be x

percentage of students who incorrectly describe the process = (100-64)%

=36%

$\frac{36}{100}*x =63$

x= 63*100/36

x=175 students.

FIRST METHOD

Number of students who correctly describe the process = $\frac{64}{100}*total number of students$

= $\frac{64}{100}*175$

Number of students that correctly describe the process = 112 students.

SECOND METHOD

Number of students who correctly describe the process = Total number of students- number of students who didn't correctly describe the process

Number of students who correctly describe the process = 175-63

Number of students who correctly describe the process = 112 students.
