OK,
this is an equilateral triangle, and by the indicators on the lines, we know the bottom angles have to be the same
we also know that angles in a triangle sum to 180
with this information we can work out the angle x
180 - 24 = 156
156/2 = 78
The answer is 78

Answer:
3.43 hours
Step-by-step explanation:
A castle has to be guarded 24 hours a day. 7 knights are ordered to split each day guard duty equally. How long will each knight spend on guard duty in one day?
From the above question:
7 knights = 24 hours
1 knight = x hours
Cross Multiply
7 knights × x hours = 1 knight × 24 hours
x hours = 1 knight × 24 hours/ 7 knights
x hours = 3.4285714286 hours
Approximately = 3.43 hours
Therefore, each knight would spend 3.43 hours on guard duty in one day
The answer should be 390=60s, assuming s is the number of shelves he would need.
By the way, if you want the answer using this formula:
390=60s
390/60=s
6.5=s
s=6.5
Answer:
t=0, 6, -4
Step-by-step explanation:
first, you can factor out t² of the equation
t²(t²-2t+24)=0, then factor the trinomial
t²(t-6)(t+4)=0, now set each factor equal to zero
t²=0, so t = 0
t-6=0, so t = 6
t+4=0, so t = -4
If you graph it, you can also see the answers.
