Answer:
a) Triangle.
b) Triangle.
c) The area is 110 cm.
Step-by-step explanation:
The shape is given because it is a cross section of a Pyramid which we can see shaded in grey.
The area is given by the base times hight devided by 2. So 10cm * 22cm/2= 110cm.
Hope this helped ;)
No, it's simplest form would be 2/5.
1 is 47 and 2 is 27 you welcome
Any number divided by 1 equals the original number.
See the attached picture:
Opposite sides of angles are equal so
x+12=4x-48
12+48=4x-x
60=3x
x=60/3
x=20
