Answer:
it is half the area of a square of side length 8
Step-by-step explanation:
area of a square = l × b
= 8 × 8
= 64 cm^2
area of a triangle = b × h ÷ 2
= 8 × 8 ÷ 2
= 64 ÷ 2
= 32 cm^2
hope you can understand ☆☆☆
Flat and idk the other one

Answer:
B
I
Step-by-step explanation:
A triangle's angles must add up to 180
68+90+x=180
158+x=180
22=x
3 and 2 must add up to 180
70+x=180
angle 2= 110
angle 2 and angle 1 have to add up to 180 as well
110+x=180
andgle 1= 70
Gropu like terms
(-1/2)x+(3/2)x-4x+3+5=
(2/2)x-4x+8=
1x-4x+8=
-3x+8
