Answer:

The area of a triangle is the space contained within its 3 sides. To find out the area of a triangle, we need to know the length of its three sides. The sides should be measured in feet (ft) for square footage calculations and if needed, converted to inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m). The formula:

Square feet to square meters: multiply ft² by 0.092903 to get m²

Square yards to square feet: multiply yd² by 9 to get ft²

Square feet to square yards: multiply ft² by 0.11111 to get yd²

Square yards to square meters: multiply yd² by 0.8

Step-by-step explanation:

nirvana33 [79]
R - Right Handed 
L - Left Handed 

R = 9L ( the number of right handed kids is equal to having 9*number of left handed kids) 
9L + L = 30  ( since total number of people in class is 30) 
10L = 30 
( Divide by 10 both sides )
L = 3 

so... There are 3 Left Handed kids and 27 Right Handed kids ( since R = 9L , R = 9(3) = 27)

A quadrilateral has angles that measure 60°, 95°, and 150°.
Nikolay [14]
The sum of angles in a quadrilateral = 360 degrees.

Let the fourth angle be x:

Therefore:  60 + 95 + 150 + x = 360

305 + x = 360

x = 360 - 305

x = 55

Option B. I hope this helps.
