Solve triangle ABC if A = 50°, a = 10, and b = 20. If no triangle exists, explain why.

Dahasolnce [82]

Answer:

No triangle exist

Step-by-step explanation:

step 1

Find the measure of angle B

Applying the law of sines

$\frac{a}{sin(A)}=\frac{b}{sin(B)}$

substitute the given values

$\frac{10}{sin(50^o)}=\frac{20}{sin(B)}$

$sin(B)=20(sin(50^o))/10$

$sin(B)=1.532$

Remember that

The maximum value of the sine is 1

therefore

No triangle exist

(3, y) and (9, -9); slope: -4/3<br>Find y<br>PLEASE HELP

For this case we have that by definition, the pendeinte of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}\\(x_ {1}, y_ {1}) :( 3, y)\\(x_ {2}, y_ {2}) :( 9, -9)$

Substituting according to the data we have:

$- \frac {4} {3} = \frac {-9-y} {9-3}\\- \frac {4} {3} = \frac {-9-y} {6}\\6 * - \frac {4} {3} = - 9-y\\-8 = -9-y\\y = -9 + 8\\y = -1$

Answer:

$y = -1$

Three partners x,y and z contribute an amount of ksh 1400000 for an investment .The profit from the investment is to be shared b

son4ous [18]

Answer:

The ratio of the contribution x:y:z is 6:8:11

Step-by-step explanation:

Firstly, we need to know the amount in which Z got

That will be 250,000-x-y

= 250,000- 60,000 - 110,000 = 80,000

So the ratio of the contribution in x:y:z will be;

60,000:110,000:80,000

= 6:11:8
