Use law of cosines
o^2=p^2+q^2-2pqCos(C)
o^2=38^2+29^2-38*29Cos(39)
o^2=1444+841-1712.83
o^2=572.17
o=23.92
Say 24 cm
Answer:
A,C and D
Step-by-step explanation:
A: 3x2=6
3x4X=12X
<em>6+12X</em>
C: 5x1=5
5x2X=10X
5+10X+1+2X
<em>6+12X</em>
D: 7x1=7
7x2X=14X
7+14X-2X-1
6+14X-2X
<em>6+12X</em>
Answer:
