Here’s the answer because I can’t do the arrow thing on phone
Answer:
Step-by-step explanation:
find the area of every face and the base
area of face 1= 2
area of face 2= 2
area of face 3 = 2
area of base 1= 1.7
7.7 in squared
area of a triangle is the base x height divided by 2
face 1- 2 x 2=4
4/2=2
2x3(theres 3 faces to a triangle) =6
area of base- 2 x 1.7= 3.4
3.2/2=1.7
add the faces and the base together
7.7
I believe d has to be the right answer. I solved the problem backward so the explanation would be confusing. Try subtracting the 22 degree angle from 180.
F( x ) = 0 => / x / = 0 => x = 0, where -2 <= 0 < 3 ;
x = 0 => f ( 0 ) = / 0 / = 0.
