This problem should not give you too much difficulty. The area of a triangle is (LxH)/2. The area of a rectangle is LxH. Calculate the area of each triangle and the three rectangles.
When added together, you should get 75.75cm².
I would show the work for you, but just work through it slowly, and you should get the same thing.
Answer:
140 degrees
Step-by-step explanation:
The center angle of a semi circumference is 180 degrees
BC 180 - 20 - 20 = 180 - 40 = 140 degrees
Answer:
-7<-6
Step-by-step explanation:
(7+21)=28
28(3-I)=
28•3 =84
28•I=28i
28/84=3,5
3,5=I
So I would round it to 340 and 40 because if the number is lower than 5 than take it DOWN to the nearest ten if it's five or above take UP to the nearest ten
Hope it helped you
