Answer:

$sinA = \frac {a} {c}$

Step-by-step explanation:

We are given a right angled triangle ABC with the side lengths a, b and c. We are to find the value of sin A.

We know that sine is the ratio of perpendicular to hypotenuse.

So considering A as our desired angle, side a will be our perpendicular while c will be the hypotenuse.

Therefore, $sinA = \frac {a} {c}$ .

$\sin(A) = \frac{BC}{AB} = \frac{a}{c}$

The sum of two consecutive integers is 81. Determine the lesser of the two numbers.

SCORPION-xisa [38]

Given that,

the two numbers are consecutive

The two numbers are

x and x + 1

Sum of the numbers = 81

x + (x + 1) = 81

x + x + 1 = 81

2x = 81 - 1

2x = 80

x = 80/2

x = 40

Therefore, the two numbers are x = 40 and x + 1 = 41

If -x < -y, then all of the following are true except?

Marysya12 [62]

Answer:

b, c, d are all false

Step-by-step explanation:

Let x=4, y=2. The given statement says ...

... -4 < -2 . . . . . a true statement.

Now, let's look at the answer choices.

... a. -4 < -2 . . . . true

... b. 2(4) < 2(2) . . . . false

... c. 4 +2 < 2 +2 . . . . false

... d. 4/2 < 2/2 . . . . false

Then "a" is true, and "b", "c", and "d" are false.
