Determine x and <B

Missing in the question: A and B are vertical angles

For vertical angles A and B,

Substitute values for A and B

Solve for x

To solve for B, substitute 8 for x in

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
