The last option is the correct answer. The sine of angle A is identical to the cosine of angle C.
Answer:
x = -11
Step-by-step explanation:
I'm assuming it's an isosceles triangle so 32 + 2x = 10;
subtract 32 from both sides;
2x = -22
x = -11
Answer:
7
Step-by-step explanation:
Answer: RS 49.8
Step-by-step explanation:
Given the following :
Fixed cost = RS 4430
Break even point = 89 units
Recall:
Break even point in units = Fixed cost ÷ contribution margin
Therefore,
Contribution margin equals;
(Fixed cost ÷ break even point in units)
= 4430 / 89
= 49.775280
= RS 49.8
Answer:
First, you have to form simultaneous equation for both of their ages in yerms of a and b :
b = 4a - 12 -------- ( 1 )
a + b = 28 -------- ( 2 )
Next, you will have to solve it by substituting ( 1 ) into ( 2 ) :
a + (4a - 12) = 28
5a - 12 = 28
5a = 28 + 12
5a = 40
a = 8
Then, substitute a = 8 into ( 1 ) :
b = 4(8) - 12
b = 32 - 12
b = 20
