Answer:
<h2>It's a right triangle. a = 5.</h2>
Step-by-step explanation:
Look at the picture.
We have the triangle 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.
We have:
<em>divide both sides by √3</em>
It's a right triangle.
Answer:
I belive its C not 100%
Step-by-step explanation:
Answer:
6.75
Step-by-step explanation:
54 cards in a deck p(8) so do 54 divided by 8 which should equal 6.75
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
