Answer:

C.

Step-by-step explanation:

Perpendicular lines are lines that intersect and form a 90 degree angle. They look like a plus sign (+). The slope of perpendicular lines are the negative reciprocals of each other, which means that the answer is C.

Hope this helps and have a great day :)

Find the missing side. round to the nearest tenth.
horrorfan [7]

Answer:

24) x = 9.2

25) x = 30.8

Step-by-step explanation:

Given

See attachment for triangles

Solving (24)

To solve for x, we make use of cosine formula

i.e.

cos(40) = adjacent ÷ hypotenuse

So, we have:

cos(40) = x ÷ 12

Multiply both sides by 12

12 cos(40) = x

12 * 0.7660 = x

x = 9.2

Solving (25)

To solve for x, we make use of sine formula

i.e.

sin(25) = opposite ÷ hypotenuse

So, we have:

sin(25) = 13 ÷ x

Multiply both sides by

x sin(25) = 13

Divide by sin(25)

x = 13 ÷ sin(25)

Using a calculator

x = 30.8

Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 5050 meters.
goblinko [34]

Answer:

The diagonal distance across the plaza is 7141.8 meter.             Step-by-step explanation:

Given : Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 5050 meters.

To find : What is the diagonal distance across the plaza?

Solution :

We have given the side of a square a=5050 m

The length of the diagonal is multiply the length of square with square root 2.

D=\sqrt{2} (a)

Substitute the value of a in the diagonal formula,

D=\sqrt{2} (5050)  

D=1.414\times 5050

D=7141.77

Nearest tenth = 7141.8 m

Therefore, The diagonal distance across the plaza is 7141.8 meter.
