Two angles from a linear pair. The measure of one angle is 15 times the measure of the other angle find the measure of each angle

Step-by-step explanation:

The measure of angle =x

15x + x=16x

linear pair=180°

16x=180°

x=180°/16

x=11.25

15x=11.25*15

15x=167.75

separate the base word from the suffix. ​

Let the tailor P work for x days and the tailor Q work for y days respectively.

Z=150x+200y

Here the problem can be formulated as an L.P.P. as follows

Minimize Z=150x+200y

Subject to the constraints

6x+10y≥60

⇒3x+5y≥30

4x+4y≥32

x+y≥8

and x≥0,y≥0

Converting them into equations we obtain the following equations

3x+5y=30,

⇒y=

5

30−3x

x 0 10 5

y 6 0 3

⇒x+y=8

y=8−x

x 0 8 5

y 8 0 3

The lines are shown on the graph paper and the feasible region (Unbounded convex) is shown shaded.

The corner points are

A(10,0),B(5,3) and C(0,8)

At the corner point the value of Z=150x+200y

At A(10,0)Z=1500

At B(5, 3), Z=150×5+200×3=750+600=1350

At C (0, 8), Z=1600

As the feasible region is unbounded, we draw the graph of the half-plane

150x+200y<1350

3x+4y<27

There is no point common with the feasible region, therefore, Z has minimum value.

Minimum value of Z is Rs. 1350 and it occurs at the point B(5,3).

Hence, the labour cost is Rs. 1350 when P works for 5 days and Q works for 3 days.
