For an acute angle 0, the equation sin(0) = cos(6) is true. What is the value of ? Show or explain your answer

weqwewe [10]

Answer:

$\theta =84$

Step-by-step explanation:

Given

$sin(\theta) = cos(6)$

Required

Find $\thata$ $\theta$

In trigonometry:

If sin(A) = cos(B), then

$A + B = 90$

So, we have:

$\theta + 6 = 90$

Collect Like Terms

$\theta + 6 -6= 90-6$

$\theta = 90-6$

$\theta =84$

425 students in the 9th, 10th, and 11th grades were asked if they ride the bus to school. The results are shown in the two-way f

Ipatiy [6.2K]

The true statements are:

44/85 of the student surveyed do not ride the bus to school
About 32% of the students are in the 9th grade

The false statements are:

64% of the students are 11th graders
134/150 of the students surveyed are in 9th or 10th grade

<h3>How to interpret the two-way frequency table</h3>

<u>The students that do not ride bus to school</u>

From the table, 220 students do not ride bus to school.

So, the proportion of students that do not ride bus to school is:

$p=\frac{220}{425}$

Simplify

$p=\frac{44}{85}$

Hence, this statement is true

<u>The 9th graders </u>

From the table, 134 students are 9th graders

So, the proportion of students that are 9th graders is:

$p=\frac{134}{425}$

Divide

$p=0.315$

Approximate, and represent as percentage

$p=32\%$

Hence, this statement is true

<u>The 11th graders </u>

From the table, 141 students are 11th graders

So, the proportion of students that are 11th graders is:

$p=\frac{141}{425}$

Divide

$p=0.331$

Approximate, and represent as percentage

$p=33\%$

Hence, this statement is false

<u>The 9th or 10th graders </u>

From the table, 134 + 150 students are 9th or 10th graders

So, the proportion of students that are 11th graders is:

$p=\frac{134 + 150}{425}$

$p=\frac{284}{425}$

Hence, this statement is false
