Answer:
47 degrees
Step-by-step explanation:
C
work:
75 is equal to 2x+15
75-15 = 60
60/2 = 30
x=30
1.50 x 7 = 10.5
0.85 x 5 = 4.25
10.5 + 4.25 = 14.75
So you can only have 7 roses . I found this out using trial and error and then adding on the correct number of carnations to make it a dozen and to make sure it equaled 14.75 .
Hope this all makes sense .
I am a little confused about the question you are trying to ask. It is an isosceles triangle because it has two sides of equal length.
The other angle would be...
180-2(55)=70 degrees
Divide the mass value (384 oz) by 16
16 oz = 1 lb
384 divided by 16= 24
