How do I solve for what is sin A for the triangle shown
PtichkaEL [24]

Option a:

sin A for the triangle is \frac{3}{5}.

Solution:

The given triangle is a right triangle.

The adjacent side to angle A is AC.

The opposite side to angle A is BC.

Hypotenuse is AB.

AC = 8, BC = 6 and AB = 10.

Using trigonometric ratio formulas,

$\sin \theta=\frac{\text { Opposite side }}{\text { Hypotenuse }}

$\sin A=\frac{BC}{AB}

$\sin A=\frac{6}{10}

Divide both numerator and denominator by 2, we get

$\sin A=\frac{6\div2}{10\div 2}

$\sin A=\frac{3}{5}

Hence sin A for the triangle is \frac{3}{5}.

Option a is the correct answer.

anzhelika [568]

Answer: D

Step-by-step explanation:

so we know the probability of drawing a 9 is 25 percent  or 1/4 because 9 is only one and doesn't repeat.

So the cards we drawn cards we drawn 2 times so multiply 1/4 times two.

1/4 * 2/1= 2/4 = 1/2

How do you find the area of a triangle
Anna007 [38]
Salutations!

How do you find the area of a triangle

To find the area of a triangle, you need to know the formula of the triangle to work it out. The following is the formula of the triangle:

hb/2 

H - height

B- Base

You need to multiply the base and height and divide it by 2.

Lets solve a question!

Find the area of a triangle with a base of 32mm and a height32 * 35 of 35mm

Area = hb/2

         = 32* 35

          = 1120

          = 1120/2

           = 56cm^2

Hope I helped (:

Have a great day!
