Answer:

x = 17

∠A = 114°

Step-by-step explanation:

In the figure attached, the complete question is shown.

From the figure, we know that:

∠A = ∠B

Replacing with the expressions, we get:

6x+12 = 3x+63

6x - 3x = 63 - 12

3x = 51

x = 51/3

x = 17

∠A = 6(17)+12

∠A = 114°

One of Shakespeare's sonnets has a verb in 11 of its 18 lines, an adjective in 13 lines, and both in 8 lines. How many lines hav

horrorfan [7]

Answer:

Step-by-step explanation:

The total number of lines, n(U) = 18

Let the number of lins with verb be n(V) = 11

Let the number of lines with adjectives be n(A) = 13

n(V n A) = 8

Find the number of lines that have a verb but no adjective, that is, n(V n A')

Mathematically, according to sets theory,

n(V) = n(V n A) + n(V n A')

So,

n(V n A') = n(V) - n(V n A) = 11 - 8 = 3.

Hence, only 3 lines have a verb but no adjectives.
