Answer:
y=15
DE=11
GF=17
Step-by-step explanation:
y*2=5*6
2y=30
y=15
5+6=11
15+2=17
I hope this helps you
at the 30-60-90 triangle has rules
30=>k
60=>k(square root of) 3
90=>2k
so in this triangle 60=> see 9
k(square root of) 3=9
k=9/(square root of) 3
2k=18/(square root of) 3
at the 45-45-90 triangle rules are
45=>2k
45=>2k
90=>[2k/(square root of 3)] (square root of) 2
x=[18/(square root of 3)].(square root of 2)
x=18(square root of 2)/square root of 3
C. best represents the equation
30÷5=6
4×5=20
for every 30 green lights there are 20 white lights
The should be 158 ways, because 9*8+8*7+6*5=158.
