An acute triangle is a triangle with<span> all three angles</span>acute<span> (less than 90°). An </span>obtuse triangle<span> is one with one </span>obtuse<span> angle (greater than 90°) and two </span>acute<span>angles. Since a </span>triangle's<span> angles must sum to 180°, no</span>triangle<span> can have more than one </span>obtuse<span> angle.</span>
The common difference is 12. However, let’s take a look at how we got there!
First take the 2nd term (23) and find the difference from the 1st term (11). The difference is 12.
Repeat this for the remaining terms…
35 - 23 = 12
47 - 35 = 12
59 - 47 = 12
The common difference is 12.
We can write an equivalent expression by factoring this polynomial.
Since the GCF for these terms is 5, we can factor out a 5.
That leaves us with each term divided by 5 inside the parenthses.
So we have 5(x + 3).
No circle can never be the perfect squares
Answer:
x=60° or 300°
Step-by-step explanation:
2cosx=1
cosx=1/2
cosx=cos60°,cos(360-60)°
cosx=cos60,cos300
either,
cosx=cos60
x=60
or,
cosx=cos300
x=300
