If 1-cosA = 1/2 , Then find the value of sinA.

zimovet [89]

Step-by-step explanation:

Given :

1- cosA = 1/2

or, CosA = 1 -1/2

Therefore ; CosA = 1/2 = b/h

According to the Pythagoras theorem,

P = root under h^2 - b^2

= root under (2)^2 - (1)^2

= root under 4 -1

= root 3

Again,

SinA = P/h

= root 3 / 2

The radius of a circular plate is 12 centimeters. What is the area, in square centimeters, of this plate? Write your Anwer using

lesya [120]

Answer:

The area of circular plate is <u>144π square centimeters</u>.

Step-by-step explanation :

<h3><u>Solution</u> :</h3>

Here, we have given that the radius of circular plate is 12 centimeters.

So, finding the area of circular plate by substituting the values in the formula :

$\longrightarrow{\pmb{\sf{Area_{(Circle)} = \pi{r}^{2}}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12)}^{2}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12 \times 12)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(144)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi \times 144}}$

$\longrightarrow{\sf{Area_{(Circle)} = 144\pi}}$

$\star{\underline{\boxed{\frak{\purple{Area_{(Circle)} = 144\pi\: {cm}^{2}}}}}}$

Hence, the area of circular plate is 144π square centimeters.

A blue boat and a red boat are on the same side of a lake and are 18 miles apart. The blue boat is 30 miles from a lighthouse on

rewona [7]

9514 1404 393

Answer:

red boat distance: 42 miles
angle at lighthouse: 22°

Step-by-step explanation:

The Law of Cosines can be used to find the distance from the red boat to the lighthouse.

b² = l² +r² -2lr·cos(B)

b² = 18² +30² +2·18·30·cos(120°) = 1764

b = √1764 = 42

The distance from the red boat to the lighthouse is 42 miles.

__

The angle at the lighthouse can be found using the law of sines.

sin(L)/l = sin(B)/b

L = arcsin(l/b·sin(B)) = arcsin(18/42·sin(120°)) ≈ 21.79°

The angle between the boats measured at the lighthouse is about 22°.
