In triangle OPQ, p = 38 cm, q = 29 cm and Angle O=39º. Find the length of o, to the nearest
Lisa [10]

Answer:

The length of o is 24 centimeters

Step-by-step explanation:

In Δ OPQ

∵ Side p is opposite to ∠P

∵ Side q is opposite to ∠Q

∵ Side o is opposite to ∠O

→ To find side o we must use the cosine rule

∴ o = \sqrt{p^{2}+q^{2}-2(p)(q).cos(O)  }

∵ p = 38 cm

∵ q = 29 cm

∵ m∠O = 39°

→ Substitute them in the rule to find o

∴ o = \sqrt{(38)^{2}+(29)^{2}-2(38)(29).cos(39)}

∴ o = 23.92008154

→ Round it to the nearest centimeter (whole number)

∴ o = 24 centimeters

∴ The length of o is 24 centimeters

solve the x:(pls help with explanation) 1. 2x/3=18 2. 1.6= x/1.5 3. 14y-8=13 4. 17+6p=9 5. x/3+1= 7/15
Darina [25.2K]

Answer:

1. X=27

2. X=2.4

3. y= 1.5

4. p=-1.33

5. X=-1.6

solution,

1. \:  \:  \frac{2x}{3}  = 18 \\  \:  \: or \: 2x = 18 \times 3(cross \: multiplication) \\  \:  \: or \: 2x = 54 \\  \:  \:  \: or \: x =  \frac{54}{2}  \\  \:  \:  \: x = 27

2. \:  \: 1.6 =  \frac{x}{1.5}  \\  \:  \: or \: x = 1.6  \times 1.5( \: cross \: multiplication) \\  \:  \:  \:  \: x = 2.4

3. \:  \: 14y - 8 = 13 \\  \:  \:  \: or \: 14y = 13 + 8 \\  \:  \: or \: 14 \: y = 21 \\  \:  \: or \: 14 \times y = 21 \\  \:  \:  \: or \: y =  \frac{21}{14}  \\  \: divide \: 21 \: and \: 14 \: by \: 7 \: you \: will \: get \\  \:or \:  y =  \frac{3}{2}  \\ y = 1.5

4. \:  \: 17 + 6p = 9 \\  \:  \: or \: 6p = 9 - 17 \\  \:  \: or \: 6p =  - 8 \\  \:  \: or \: p =  \frac{ - 8}{6}  \\  \:  \: or \: p =  \frac{ - 4}{3}  \\  \:  \: p =  - 1.33 \\

5. \:  \:  \frac{x}{3}  + 1 =  \frac{7}{15}  \\  \: or \:  \frac{x + 1 \times 3}{3}  =  \frac{7}{15}  \\  \:  \: or \:  \frac{x + 3}{3}  =  \frac{7}{15}  \\  \: or \: 15(x + 3) = 7 \times 3( \: cross \: multiplication) \\  \:  \: or \: 15x + 45 = 21 \\  \:  \: or \: 15x = 21 - 45 \\  \:  \: or \: 15x =  - 24 \\  \:  \: or \: x =  \frac{ - 24}{15}  \\  \: divide \:  - 24 \: and \: 15 \: by \: 3 \\  \: or \: x =  \frac{ - 8}{5}  \\ x =  - 1.6

Hope this helps ...

Good luck on your assignment..
