Answer:
I think so
Step-by-step explanation:
The last option is the correct answer. The sine of angle A is identical to the cosine of angle C.
He got a discount of 32%, and saved 64$,
let the total amount without discount be x
according to the formula
32$=64×100/x
x=64×100/32
x=200$
Essentially, what you need to do is ensure that both sides cancel each other out to make 0 = 0
An example:
2(x + y) + 4 = (4x + 4y + 8)/2
2x + 2y + 4 = 2x + 2y + 4
0 = 0
C - is a hypotenuse,
so we can use Pythagorean theorem.
c² =a² +b²
c² = 8²+12²=64 + 144 = 16*4 +16*9=16(4+9) =16*13
c²=16*13
c=√(16*13)=√16*√13=4√13
c=4√13
Answer C. 4√13
