Given b = {a, l, g, e, b, r} and c = {m, y, t, h}, find b ∪ c. {} {a} {a, b, e, g, h, l, m, r, t, y}

B ∪ C={a, b, e, g, h, l, m, r, t, y}

Step-by-step explanation:

Given B = {a, l, g, e, b, r} and C = {m, y, t, h}

B ∪ C means B union C

To find the union of B  and C we combine all the data in both sets

When the data is repeating then we put it only once

Put all the characters inside B  and C in single group to get the union of B and C

B ∪ C={a, l, g, e, b, r,m, y, t, h}

B ∪ C={a, b, e, g, h, l, m, r, t, y}

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
