Answer:
50 degrees
Step-by-step explanation:
because it is a parallelogram, angle B = angle D, and angle C = angle A
that means we have 130(2) = 260 degrees that we know.
the total interior angles of a parallelogram = 360
360 - 260 = 100 degrees left. BUT because those are the total amount of angles left, those are angles A and C combined, so you have to divide 100 in half to get the angle A/ angle DAB
100/2 = 50 degrees. hope this helps! leave a question if you are still confused.
Hey there! I'm happy to help!
First, let's find the radius. The radius is half of the diameter.
8.4/2=4.2
Here's how to find the area of a circle.
Square the radius.
4.2²=17.64
And multiply by pi (3.14 in our case)
17.64(3.14)=55.3896
We round to the nearest tenth, giving us an area of 55.4 ft²
Have a wonderful day! :D
