Answer: 12
Step-by-step explanation:
since it’s isosceles, the bottom two angles are equal so just subtract 156 from 180 and then divide that by 2.
1. All you have to do to find the area of the figure. IS first find the area of the rectangle. This is easy because all you have to do is base times height.
22 x 17 = 374
Now to find the area of the triangle all you have to do is do base times height like a rectangle, but then divide it by 2 afterwords.
19 x 12 = 228 ÷ 2 = 114.
Now add the two area's together:
374 + 114 = 488.
Just do the same with the one below, I've altered the pic a bit to make it easier.
Charlie must have had 11 rice cakes
You multiply 120 times 3 to get 360
then 800- 360 = 440
440 divided my 40 = 11
It is B. the differences are added together
