Answer:
60 degrees
Step-by-step explanation:
because two inner angles equals the opposite side's outer angle, we can do this
3y + 13 + 4y = 118
we combine like terms
7y + 13 = 118
subtract
7y = 105
and then divide
y = 15
then we do the equation for A's angle
4(15) = 60
Answer:
c
Step-by-step explanation:
I think this is right
20/5 = 4 half lives
so
<span>300 * (1/2)^4
</span>= 300 * 0.0625
=18.75 grams
120 + 32x < = 720....with x being the number of seats
32x < = 720 - 120
32x < = 600
x < = 600 / 32
x < = 18.75
