Answer:
161.8cm²
Step-by-step explanation:
solve for height which is the opposite
opp=x
sin(theata)= opp./hyp.
sin23=x/30
x=30×sin23
x=11.72cm
height=opposite
height=11.72cm
base=adjacent
base=27.6cm
½of 27.6cm=13.8
13.8cm×11.72cm=161.74 (2d.p)
161.74 rounded to the nearest tenths= 161.7

Answer:
option D
Place the point of the compass on point A and draw an arc across AB
Step-by-step explanation:
Following are the steps to follow to draw a perpendicular bisector of AB
Step 1
Place the compass at one end of line segment and adjust the compass to slightly longer than half of the line AB.
Step 2
Place compass on point A and draw arcs above and below the lineAB.
Step 3
Keeping the same compass width, draw arcs from point B.
Step 4
Place ruler where the arcs cross, and draw the line segment.
