Answer:

<h2>A.  ∠Q = 63.4°,  PQ = 2,  PQ = 4.47</h2>

Step-by-step explanation:

∠Q = 180 - 90 - 26.6

∠Q = 63.4°

<u>side PQ</u>

use opp. = tanФ (adj.)

PQ = tan(26.6) x 4

PQ = 2

<u>side QO</u>

use Pythagorean

PQ² = PO² + PQ²

PQ² = 4² + 2²

PQ = \sqrt{16 + 4}

PQ = 4.47

Answer:

A

Step-by-step explanation:

O = 26.6

P is a right angle so:

P = 90

angles PQO = 180

To determine Q: triangle total - (P + O)

180 - (90 + 26.6)

180 - 116.6 = 63.4

Q = 63.4

To determine side lengths: a^2 + b^2 = c^2

4^2 + b^2 = c^2

*Variable c is always hypotenuse*

Need more information so find either b or c through SOH, CAH, TOA

SOH: sine = opposite/hypotenuse

CAH: cos = adjacent/hypotenuse

TOA: tan = opposite/adjacent

tan26.6/1 = b/4

Cross multiply

1 × b = 4 × tan26.6

b = 4tan26.6

b = 2.003050791

b is about 2

b = PQ

PQ = 2

Plug b value into pythagorean theorm

4^2 + 2^2 = c^2

16 + 4 = c^2

20 = c^2

square root of 20 = square root of c^2

4.47213.... = c

c is about 4.47

c = QO

Sally has twice as many dimes as nickels. The total value is $3.50 how many nickels and dimes does she have?
Murljashka [212]
D=2n
.05n+.1d=3.5
I multiplied the nickels and dimes by these values because that is their actual monetary value 
.05n=3.5-.1d
multiply everything by 20
n=70-2d
d/2=70-2d
.5d+2d=70 
2.5d=70
d=28 
n=14 
so there are <u>28 dimes and 14 nickels 
</u>
checking this answer 
28 dimes = $2.8
14 nickels = .70
2.8+.7=3.5

What is k/5.2 + 81.9= 47.2
weqwewe [10]
Solution for k/5.2+81.9=47.2 equation:
<span>k in (-oo:+oo)

k/5.2+81.9 = 47.2 // - 47.2

k/5.2-47.2+81.9 = 0

0.19230769*k-47.2+81.9 = 0 // - 81.9-47.2

0.19230769*k = -(81.9-47.2) // : 0.19230769

k = (-(81.9-47.2))/0.19230769

k = 5.20000006*(47.2-81.9)

k = 5.20000006*(47.2-81.9)

Always Practice, It makes Perfect! Anyways, I hope I helped... It would be nice if you can answer mine too, But you dont have to! ;) </span><span>brainly.com/question/253764
