Answer:
21 (PLEASE GIVE BRAINLIEST)
Step-by-step explanation:
we have the base, but we need the height
we will find it using the area:
height = 336 / 16 = 21
we know that
area larger triangle (DEF)=[scale factor]²*area smaller triangle (ABC)
solve for scale factor
scale factor=√[area larger triangle/area smaller triangle]
scale factor=√[144/100]------> scale factor=1.2
therefore
measure EF=scale factor *measure BC
solve for measure BC
measure BC=measure EF/scale factor-------> 15/1.2------> 12.5 cm
the answer is
measure BC is 12.5 cm
Step-by-step explanation:
divide each side by 5 is the correct justification please give thanks
