Answer:
Step-by-step explanation:
Left triangle: it has two congruent legs because has an angle of 45 degrees
AB = cm
the triangle on the the right is half on an equilateral one
BC = 12 cm
CH = 6√3 cm
AC= (6 + 6√3) cm
2p = 6 + 6√3 + 12 + 6√2 = 18 + 6√3 + 6√2 = 6(3 + √3 + √2) cm
Area = [6(1+√3) * 6]/2 = 18(1+√3) cm^2
If you’re both working at a constant rate, then he would have one hour left when you go to help him. Since there are two of you, you accomplish the task twice as fast, in 30 minutes
X is the short piece
(3•x-1)+x=31
4x=31+1
X=32/4=8
Short piece is 8
Long piece is 3•8-1=23
Check 8+23=31 ✔️
