n a right triangle, the tangent of angle A is 912 and the cosine of angle A is 1215. Based on these values, what is the sine of angle A? A 915 B 1516 C 1115 D 11120

Answers

Answer 1

Answer:

Answer:

Option A $sin(A)=(9)/(15)$

Step-by-step explanation:

we know that

$tan(A)=sin(A)/cos(A)$

Solve for sin(A)

$sin(A)=tan(A)cos(A)$

we have

$tan(A)=(9)/(12)$

$cos(A)=(12)/(15)$

substitute

$sin(A)=(9)/(12)((12)/(15))$

$sin(A)=(9)/(15)$

Answer 2

Answer:

Final answer:

The sine of angle A can be found using the relationship between the tangent and cosine of angle A. By substituting the given values into the sine identity, we can determine that the sine of angle A is 915.

Explanation:

To find the sine of angle A, we can use the trigonometric identity: sin A = opposite/hypotenuse. Given that the tangent of angle A is 912 and the cosine of angle A is 1215, we can use the relationship between these trigonometric functions. Since tan A = opposite/adjacent and cos A = adjacent/hypotenuse, we can substitute these values into the identity to solve for the sine of angle A.

From tan A = 912, we can rearrange the equation to get opposite/adjacent = 912.

From cos A = 1215, we can rearrange the equation to get adjacent/hypotenuse = 1215.

Substituting these values into the sine identity, we get sin A = opposite/hypotenuse = (912)(1215).

Therefore, the sine of angle A is 915.

Suppose is a semester that 38% of students at a college failed mathematics, 27% failed physics, and 9% failed both. A student is selected at random.a)If a student failed physics, what is the probability that he or she failed math?
b)If a student failed math, what is the probability he or she failed physics?
c)What is the probability that he or she failed math or physics?

Answers

Hello,

A) failed in Phys: 27 failed in Math ==> intersection : 9/27=1/3

B)Failed in Math 38 ,failed in Phys ==>9/38

C) M∪P=M+P-M∩P= (38+27-9)/100=56/100=14/25

x + y = 3
- x - x
y = -x + 3

y - y₁ = m(x - x₁)
y - (-1) = -1[x - (-1)]
y + 1 = -1(x + 1)
y + 1 = -1(x) - 1(1)
y + 1 = -x - 1
- 1 - 1
y = -x - 2
