Answer:
pretty sure x=0 if not it might be infinite solutions but im pretty sure its just 0.
I plugged it in and i think it works
Step-by-step explanation:
Answer:
15%
Step-by-step explanation:
Let
Selling price = SP
Cost price = CP
If CP = 100
Profit = selling price - cost price
x% = SP - x% of 100
x% + 100x% = SP
SP = 100 (1 + x/100) (1)
If CP = 92
SP = 92 (1+ {x+10}/100)
Equate both SP
100 (1 + x/100) = 92 (1+ {x+10}/100)
100 + x = 92 + [{23/25} * (x+10)]
{2/25}x = 30/25
x = 30/25 ÷ 2/25
= 30/25 × 25/2
= 30/2
x = 15%
Well, since its isoceles triangle so two equal sides. its either 3 or 7. There is a theorem that states two sides added must be greater than the third. so if the third side is 3. it would be 3+3=6, less than 7, incorrect. therefore the correct side is 7. so the sides are 3, 7, 7. you can add them to confirm the theorem.
For this case we will define the following:
A, B: are the values of the triangle angles
a, b: are the values of the lengths of the sides opposite the angles A, B.
We then have to use the law of the sine:

Clearing the angle B we have:

Substituting values we have:
Answer:
the following is true:
A. angle B=38.08 degrees
