Step-by-step explanation:
90+81+mising angle=180, missing angle is 9
Answer:
m∠BOC = 53°
Step-by-step explanation:
The definition of an angle bisector is that it divides an angle into two congruent angles. ∠AOC is divided by angle bisector OB into angles ∠AOB and ∠BOC, hence those two angles are congruent.
m∠AOB = m∠BOC = 53°
3 ways
1 - 6 packs of 6 cookies (6*6 = 36)
2 - 2 packs of 18 cookies (2*18 = 36)
3 - 3 packs of 6 cookies and 1 pack of 18 cookies (3*6 = 18 + 18 = 36)
Width -w
length l= 2*w+5
perimeter P=2w+2l, 52=2w+2l
system of equations:
52=2w+2l ------> 26 =w+l (1)
l= 2*w+5 (2)
substitute value of l from second equation into the 1st
26=w+2w+5
26=3w+5
21=3w
w=7
l=2w+5, l=2*7+5, l=19
Answer:
system
52=2w+2l
l= 2*w+5
length 19 ft, width 7 ft
