In the triangle above, what is sin A

Shkiper50 [21]

Answer:

$\large\boxed{\sf sin(A)=0.5}$

Step-by-step explanation:

A right angled triangle is given to us and we would like to find out the value of sin(A) .

From the triangle we can see that the measure of angle BAC is 30° . Therefore ,

$\longrightarrow A = 30^o$

On using sin both sides ,

$\longrightarrow sin(A) = sin30^o$

As we know that the value of sin30° = 1/2. So;

$\longrightarrow sin(A)=\dfrac{1}{2}$

Simplify by converting it into decimal ,

$\longrightarrow \underline{\underline{sin(A) = 0.5}}$

Hence option B is correct .

And we are done!

Find HY if YL=9. nobody has shown me how to do this the last two weeks

Alekssandra [29.7K]

Step-by-step explanation:

(a) Your computer may be programmed to allocate borderline cases to the

next group down, or the next group up; and it may or may not manage

to follow this rule consistently, depending on its handling of the numbers

involved. Following a rule which says 'move borderline cases to the next

group up', these are the five classifications.

(i) 1.0-1.2 1.2-1.4 1.4-1.6 1.6-1.8 1.8-2.0 2.0-2.2 2.2-2.4

(ii) 1.0-1.3 1.3-1.6 1.6-1.9 1.9-2.2 2.2-2.5

10 6 10 5 6

2.5-2.8 2.8-3.1 3.1-3.4 3.4-3.7

PLZ HELP Explain your REASON and I have to turn this in in like 15 minutes PLZZZZZZ

Ghella [55]

Answer:

The watermelon weighs more.

Step-by-step explanation:

I know this because 1 kilogram is equal to 2.20462 pounds. This means that 7.5 kilograms weighs as much as 16.5347 pounds. 16.5347 is greater than 12, so this means the watermelon weighs more.

Find the square. (1/4A + 1/4B)^2 a) 1/16A^2 + 1/8AB + 1/16B^2 b) 1/4A^2 + 1/8AB + 1/4B^2

alisha [4.7K]

$(a + b)^2 = a^2 + 2ab + b^2$

$(\dfrac{1}{4}A + \dfrac{1}{4}B)^2 =$

$= \dfrac{1}{16}A^2 + \dfrac{1}{8}AB + \dfrac{1}{16}B^2$

Answer: A.

Another way to solve by factoring 1/4.

$(\dfrac{1}{4}A + \dfrac{1}{4}B)^2 =$

$= [\dfrac{1}{4}(A + B)]^2$

$= (\dfrac{1}{4})^2(A + B)^2$

$= \dfrac{1}{16}(A^2 + 2AB + B^2)$

$= \dfrac{1}{16}A^2 + \dfrac{1}{16}2AB + \dfrac{1}{16}B)^2$

$= \dfrac{1}{16}A^2 + \dfrac{1}{8}AB + \dfrac{1}{16}B)^2$
