Answer :

AB = 48.88

Step-by-step explanation:

We will use the sin fulmera

\frac{ \sin(134°) }{ab}  =  \frac{ \sin(18°) }{21}  \\  \\ ab = 48.88

I hope that is useful for you :)

Answer:

48.9

Step-by-step explanation:

\frac{A}{sinA}=\frac{B}{sinB} =\frac{C}{sinC}   (you can flip the equation around)

\frac{21}{sin18} = \frac{AB}{sin134}

AB=\frac{21*134}{sin18}= 48.88448235

Sorry for the late answer I was distracted

If a 24-kg mass stretches a spring 15 cm, what mass will stretch the spring 10 cm
natulia [17]

Answer:

<h2>16kg</h2>

Step-by-step explanation:

 This problem is borers on elasticity of materials.

according to Hooke's law,<em> "provided the elastic limit of an elastic material is not exceeded the the extension e is directly proportional to the applied force."</em>

F= ke

where F is the applied force in N

          k is the spring constant N/m

          e is the extension in meters

Given data

mass m= 24kg

extensnion=15cm in meters= \frac{15}{100}= 0.15m

we can solve for the spring constant k

we also know that the force F = mg

assuming g=9.81m/s^{2}

therefore

24*9.81=k*0.15\\235.44=k*0.15\\k=\frac{235.44}{0.15} \\k=1569.6N/m\\

We can use this value of k to solve for the mass that will cause an extension of  10cm= 0.1m

x*9.81=1569.6*0.1\\\\x= \frac{156.96}{9.81} \\\x= 16kg

You read 9.75 pages in your science book and 24.5 pages of a play for English class. It takes you 1.2 minutes to read each page
Sladkaya [172]
9.75 * 1.2 = 11.7
24.5 * .8 = 19.6

11.7+19.6= 31.3 minutes

hope this helped :)

Four times the sum of a number and ter is the same as one-hundred added to eight
AfilCa [17]

Answer:

GIVE BRAINLIEST PLZ

I DONT NEED THNX

x = -15

Step-by-step explanation:

1) Four times sum of a number and 10

4(x + 10)

2) is equal to 100 added to 8 times the number

4(x+10) = 8x + 100

x + 10 = 2x + 25

-15 = x
