Step-by-step explanation:
the easiest approach seems to be the law of sines :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the angles are always opposite of each other.
we have here a right-angled triangle, so the angle opposite of 10 is 90 degrees.
10/sin(90) = 10/1 = 10 = y/sin(37)
y = 10×sin(37) = 6.018150232 ≈ 6.0
what is b? from the first equation in the system, y + 2 = b.
8 x 1 = 8
8 x 1/2 = 4
8+4 =12
therefore, 8 x 1 1/2 = 12
So a number (x because unknown) divided by 40 (x divided into 40 parts or x/40) has a quotient of 6 with a remainder of 16 (answer=6 with 16 remainder)
remember that remainder is not involved in division, just leftover
x/40=6+16 remainder
to get rid of the fraction, multiply the whole equation by 40 and add the remainder (since it wasn't involved in division)
x=240+16
x=256
check: use calculator/head
number=256
