Answer:

158 degrees

Step-by-step explanation:

Here, we want to find the sum of the two angles.

If A is a supplement of B, it means that adding A and B together will yield 180 degrees

Mathematically;

A + B = 180

A + 124 = 180

A = 180-124

A = 56

Also, A is a complement of C

This means that adding A to C yields 90

A + C = 90

C = 90- A = 90 -56 = 34

Thus B + C = 34 + 124 = 158

Answer:

The biggest profit that can be obtained by the shop owner= IDR 2,750,000.

Step-by-step explanation:

We need to form a LPP( Linear Programming Problem) for the following problem and solve it to get the maximize the profit.

Let x denote the number of men's shoe and y denote the number of female shoes.

Maximize z= 10000x+5000y----------(1)

x≥100 ( since a shoe store owner wants to fill his shop with at least 100 pairs of men's shoes )

y≥150 (at least 150 pairs of women's shoes).

also x+y≤400 (The store can only accommodate 400 pairs of shoes).

x≤150 (male shoes should not exceed 150 pairs).

⇒ 100≤x≤150

Hence the optimal solution of an LPP always lie on the end points.

We have end points as:

(100,300), (150,250), (100,150),(150,150).

by putting these value in equation (1) we see which give the maximum solution.

for (100,300) i.e. x=100 and y=300: z=2,500,000

for (150,250) i.e. x=150 and y=250: z=2,750,000

for (100,150) i.e. x=100 and y=150: z=1,750,000

for (150,150) i.e. x=150 and y=150: z=2,250,000

Hence maximum profit is obtained at x=100 and y=300.

i.e. to maximize the profit:

Number of men's shoes to be kept in store=100

and number of women's shoes to be kept in store=300

The biggest profit that can be obtained by the shop owner= IDR 2,750,000.
