Find the value of x.

nadya68 [22]

Answer:

127 degrees

Step-by-step explanation:

1. Find the angle next to "x" using the fact that all the angles in a triangle add to 180 degrees.

180-30-97 = 53

2. Angle X and the angle that is 53 degrees are supplementary meaning they will add to 180 degrees since it's on a line

180-53=57

The new post office has an area that is 6.5 times the area of the old post office. Let p represent the area of the old post offi

IrinaK [193]

Answer:

$Area = 6.5p$

Step-by-step explanation:

Given

$Area\ of\ Old = p$

$Area\ of\ New = 6.5 * Area\ of\ Old$

Required

Write an expression for the area of new post office

From the question, we have the following:

$Area\ of\ Old = p$

and

$Area\ of\ New = 6.5 * Area\ of\ Old$

Substitute p for Area of Old in the second equation

$Area\ of\ New = 6.5 * p$

$Area\ of\ New = 6.5 p$

Hence, the expression is:

$Area = 6.5p$
