Answer:

Question 5: y = 6.69 ft

Question 6: z = 12.52 in

Step-by-step explanation:

Question 5

In the right triangle shown, with respect to the angle given, y is the side that is "opposite" and the known side (15) is the "hypotenuse".

Note: The side opposite of right angle is the hypotenuse

Which trigonometric ratio relates "opposite" and "hypotenuse"? It is "SINE".

Let's setup the ratio and solve for y:

$Sin(26.5)=\frac{y}{15}\\y=15*Sin(26.5)\\y=6.69$

So,

y = 6.69 feet

Question 6

With relation to the angle given, we have the "adjacent" side and the "hypotenuse".

Which trigonometric ratio relates "adjacent" with "hypotenuse"?

It is COSINE!

We can set up a ratio as the previous question and solve for z:

$Cos(37)=\frac{10}{z}\\z=\frac{10}{Cos(37)}\\z=12.52$

So,

z = 12.52 inches

For the question I just asked

guajiro [1.7K]

Answer:

a = 36

Step-by-step explanation:

We use pythagoras theorem here.

h = 60

p = 48

b = a

h² = p² + b²

60² = 48² + b²

3600 = 2304 + b²

b² = 3600 - 2304

b² = 1296

b = 36

If x equals 7, then find the matching value for y. -2x-2y=-2

mihalych1998 [28]

Y = -6.
-2(7)-2y=-2

-14-2y=-2

you need to move -14 to the other side by canceling out -14 with +14, and add +14 to -2, giving you -2y=12. -2/12=-6

Aladdin had two envelopes to start. He bought three packs of

Stells [14]

Since it starts with 2 envelopes, subtract 2 from 17 to get how many and in all 3 packs.
17 - 2 = 15
Now, we divide that number by 3 to get how many are in each envelope.
15 / 3 = 5
There are 5 envelopes in each pack.

1.)Painting Jane is painting one wall of her living room. The wall is rectangular, 13 feet wide by 9 feet high. What is the area

antiseptic1488 [7]

Answer:

1. $117 ft^{2}$

2. $54 ft^{2}$

3. $1,428 ft^{2}$

4. $644 ft^{2}$

5. $4,700 ft^{2}$

6. $57,600 ft^{2}$

Step-by-step explanation:

First use $A = w*l$

$w = width$

$l = length$

It doesn't have to be $A = w*l$ , it could be $A = l*w$ . It will be the same answer.

1. $3 ft * 9 ft = 117 ft^{2}$

2. $3 ft * 18 ft = 54 ft^{2}$

3. $42 ft * 34 ft = 1,428 ft^{2}$

4. $23 ft * 28 ft = 644 ft^{2}$

5. $94 ft * 50 ft = 4,700 ft^{2}$

6. $360 ft*160 ft = 57,600 ft^{2}$
