Answer:
The area is 48 cm^2
Step-by-step explanation:
The formula for area of a triangle is
A = 1/2 b*h
A = 1/2 * 8cm*12cm
A = 1/2 *96cm^2
A = 48 cm^2
The area is 48 cm^2
I'm assuming this means 3g+45=4g=84.
So, just move like numbers near each other. This way, you get 4g-3g=45-84, which means g= -39.
It would be positive one. Go up one over four then down one over four.
Exterior angles of polygons always add up to 360 degrees.
A pentagon has 5 sides, so divide 360 degrees by 5 sides.
360/5 = 72
One exterior angle of a regular pentagon (all 5 sides and angles are equal) is 72 degrees.
