Find sin A for the triangle below. Give the exact value as an expression and an approximation to the nearest ten-thousandth. Not
Feliz [49]

the exact value of sin A  to the nearest ten- thousandth is 0. 6625

<h3>Using the pythagorean theorem</h3>

a² + b² = c²

The opposite side is unknown, so use the pythagorean theorem to find it

c = hypotenuse = 4

a= opposite site = ?

b= adjacent side = 3

Substitute into the formula

4² = a² + 3²

16 = a² + 9

a² = 16 -9 = 7

Find the square root

a =√7 = 2. 65

To find Sin A, use

Sin A = opposite side ÷ hypotenuse

Sin A = 2. 65 ÷ 4 = 0. 6625

Thus,  the value of sin A is 0. 6625

allochka39001 [22]

9514 1404 393

Answer:

  a = 5/4

Step-by-step explanation:

To make the second number in this ratio be 1, you need to multiply the whole ratio by 7/4:

  (7/4)(5/7) : (7/4)(4/7) = 5/4 : 1 = a : 1

  a = 5/4

Graph the inequality. -8 &lt; y + 2x &lt; 14
kap26 [50]

Answer:

Step-by-step explanation:

Split it into 2 inequalities:

-8 < y + 2x

y + 2x < 14

Isolate y , subtract 2x from first and then from second

-8 -2x < y

y < 14 -2x

Rewrite it so it looks pretty?

y > -2x-8

y < -2x +14

You can use the calculator to graph each inequality.

The solution or the system is the area where the 2 solutions for each line overlap.
