Answer:
10
Step-by-step explanation:
Your scale factor is 3/2, because when you compare AC and DF, the ration is 18/12, or 3/2. We can set up a proportion:
3/2=15/x
We cross multiplu
3x=30
x=10
So, the length of DE is 10 units.
Hope this helps!
A
because c and g are same and g and e are complementary.
Answer:
x= -7 / 6
Step-by-step explanation:
m<M + m<N = 180°
11x + 6x - 7 = 180
11x + 6x = 180 + 7
17x = 187
x = 187 : 17 = 11
m<M = m<O = 11x = 11 · 11 = <span>121°
</span>m<N = m<L = 6x-7 = 6 · 11 -7 = 66 - 7 = <span>59°
</span><span>Check : 121° + 59° = 180° OK !
</span>
