Answer:
p = 30
angles 30°, 45°; exterior: 75°
Step-by-step explanation:
The exterior angle is equal to the sum of the remote interior angle:
3p -15 = p + (p +15)
p = 30 . . . . . . . . . . . . . add 15-2p
The interior angles are 30°, 45°; the exterior angle is 75°.
Hello from MrBillDoesMath!
Answer: Yes, (8 1/2) /`17 = ( 17 11/12) /23
** I think you meant 11 1/2 is to 23 NOT 17 11 1/2 is to 23"
Discussion:
First, 8 1/2 = 17/2 and
(17/2
) / 17 = 1/2
Second 11 1/2 = 23/2 and
(23/2)/ 23 = 1/2
IN other words, the ratiors are the same:
8 1/2 11 1/2
------- = -------
17 23
Thank you,

Answer:
19 red beads
Step-by-step explanation:
We first need to find a common denominator of 4/9, 1/5 and 1/4.
The common denominator is 180. Like in an expression, what we do to one side we have to do to the other.
Silver - 180/9 = 20 ; 20*4 = 80 so there are roughly 80 sliver beads.
Gold - 180/5 = 36 ; 36*1 = 36 so there are roughly 36 gold beads.
Blue - 180/4 = 45 ; 45*1 = 45 so there are roughly 56 blue beads.
180 - (silver+gold+blue) = red beads
180-161 = 19 red beads b/c ----->
80+36+45+19 = 180
