Answer: 5 Vertices
Step-by-step explanation: I believe if it had 4 faces and 8 edges it would have 5 vertices.
So you have a right angle triangle. You need to use trig for this, as you have two values you can figure out a third.
You know that you have
90 deg. angle
19 deg. angle
Therefor you have 71 deg. angle
sin19 = x/15
15sin19 = x
x = 2.2
Now do Pythagoras c^2-b^2=a^2
a = 14.8
So the sides are 2.2 and 14.8 units long. (If these numbers are wrong tell me and I'll edit answer)
Answer: (3a+b)⋅(9a 2
−3ab+b2 )
Step-by-step explanation:
Answer:
0.03
Step-by-step explanation:
fraction = part/whole
= 27/900
= 3/100
=0.03
decimal value = 0.03
