x = 65

Explanation:

We have a pair of vertical angles. The angles do not need to align vertically to be considered vertical angles. They simply just need to be opposite one another in this X configuration as the diagram shows.

Vertical angles are always congruent.

Set the expressions equal to one another. Solve for x.

2x+15 = 145

2x = 145-15 ... subtracting 15 from both sides

2x = 130

x = 130/2 dividing both sides by 2

x = 65

Step-by-step explanation:

2x + 15 = 145

2x + 15 - 15 = 145 - 15

2x = 130

2x/2 = 130/2

x = 65

a. $7\div 2$

Step-by-step explanation:

We have been given an expression $6\frac{3}{4}\div 1\frac{2}{3}$ . We are asked to find the best estimate for our given expression.

First of all let us convert our given mixed fractions into decimal as shown below:

$6\frac{3}{4}\rightarrow \frac{6\times 4+3}{4}=\frac{24+3}{4}=\frac{27}{4}=6.75$

$1\frac{2}{3}\rightarrow \frac{1\times 3+2}{3}=\frac{3+2}{3}=\frac{5}{3}=1.666$

Upon rounding our numbers to nearest whole number we will get,

$6\frac{3}{4}=6.75\approx 7$

$1\frac{2}{3}=1.66\approx 2$

Therefore, our required expression will be $7\div 2$ and option 'a' is the correct choice.
