The angle sum of a triangle is 180 degrees
So add all the angles inside and equate it to 180: 5x+2x+3x= 180
10x=180
x= 18

Because you’re finding angle L, which is 3x, and we find what the numerical value of x is
Angle L = 3x18 = 54.
Hope this helps!

Answer:Angle L = 54 degrees

Step-by-step explanation:

The given triangle has unequal sides and unequal angles. This means that it is a scalene triangle. The sum of angles in a triangle is 180 degrees. This means that

Angle L + angle K + angle J = 180 degrees. Therefore

5x + 2x + 3x = 180 degrees

10x = 180

Dividing the left hand side of the equation and the right hand side of the equation by 10, it becomes

10x/10 = 180/10

x = 18

Angle L = 3x = 3 × 18 = 54 degrees.

HELPPP The number of members in the Triathlon Club was 36 in 2001 and has increased by 20% each year. Which exponential growth m

levacccp [35]

Answer:

C. y=36(1.2)t

Step-by-step explanation:

The number of members in the Club in t years after 2001 is given by an equation in the following format:

$y = y(0)(1+r)^{t}$

In which y(0) is the number of members in 2001 and r is the growth rate, as a decimal.

The number of members in the Triathlon Club was 36 in 2001 and has increased by 20% each year.

This means that $y(0) = 36, r = 0.2$

$y = y(0)(1+r)^{t}$

$y = 36(1+0.2)^{t}$

$y = 36(1.2)^{t}$

The correct answer is C.

Daphane gave away 3 more than half of her apples. she gave away 17 apples in all. how many apples did daphne have originally?

inn [45]

Well 17-3 gets you 14 which would be half of her apples. 14x2=28 therefore, Daphne originally had 28 apples. She gave away 17 which means she kept 11 for herself

Integrate [0, 1/2] xcos(pi*x).

elena-14-01-66 [18.8K]

To answer your question, this could be the possible answer and i hope you understand and interpret it correctly:
<span>[Integrate [0, 1/2] xcos(pi*x
let u=x so that du=dx
and v=intgral cos (xpi)dx
v=(1/pi)sin(pi*x)
integration by parts
uv-itgral[0,1/2]vdu just plug ins
(1/pi)sinpi*x]-(1/pi)itgrlsin(pi*x)dx from 0 to 1/2
(1/pi)x sinpi*x - (1/pi)[-(1/pi) cos pi*x] from 0 to 1/2
=(1/2pi)+(1/pi^2)[cos pi*x/2-cos 0]
=1/2pi - 1/2pi^2
=(pi-2)/2pi^2 ans</span>

The probability of A is 1/6 and the probability of B is 1/2. what is the probability of A or B or both happening?

Damm [24]

Answer:

$p(a \: or \: b) = p(a) + p(b) - p(a \: and \: b) \\ p(a \: and \: b) = p(a)p(b)$

Write the above equation in capital in your case, all you need to do is plug in your fractions...

Bruce wants to make 50 ml of an alcohol solution with a 12% concentration. He has a 10% alcohol solution and a 15% alcohol solut

Inessa05 [86]

The equation is 0.1x + 0.15(50-x)=1.20(50)

Step-by-step explanation:

Here you need 50ml of 12% alcohol solution.

You have 10% and 15% alcohol solutions.

Take volume of 10% alcohol solution to be x ml

Take volume of 15% alcohol solution to be y ml

Form equations;

x+y=50 ml--------------------------equation 1

0.1x +0.15 y= 12% of 50

0.1x+0.15y=6-----------------------equation 2

Now you have simultaneous equations, use a graph tool to solve for values of x and y as attached.

or use the mixture equation the get value of x

0.1x + 0.15(50-x)=1.20(50)

The values of x and y are ;

(x,y) (30,20) which means;

y is 20 ml of 15% alcohol

x is 30 ml of 10% alcohol
