Find a counterexample to show that the statement is false. Assume all sets are subsets of a universal set U = {1, 2, 3, 4, 5}. (

natka813 [3]

Answer:

For subsets A={1,2},B={2,3},C={1,2 5} of U = {1, 2, 3, 4, 5}.

A ∪ (B − C) = (A ∪ B) − (A ∪ C) does not hold.

Step-By-Step Explanation:

U = {1, 2, 3, 4, 5}.

A={1,2}

B={2,3}

C={1,2 5}

For the Left Hand Side

B-C={3}

A ∪ (B − C)= {1,2} ∪ {3} ={1,2,3}

Likewise, the Right Hand Side:

(A ∪ B)={1,2,3}

(A ∪ C)={1,2,5}

(A ∪ B)- (A ∪ C)= {1,2,3}-{1,2,5}={3}

Since, {1,2,3} ≠ {3}, A ∪ (B − C) = (A ∪ B) − (A ∪ C) does not hold.

Iteru [2.4K]

Answer:

$\sf adjacent = 4.5 \ ft$

Given:

opposite side: 13 ft
adjacent unknown
angle of 71°

using tan rule:

$\sf tan(x) = \dfrac{opposite}{adjacent}$

$\hookrightarrow \sf tan(71) = \dfrac{13}{adjacent}$

$\hookrightarrow \sf adjacent = \dfrac{13}{tan(71) }$

$\hookrightarrow \sf adjacent = 4.5$
