Calculate −2 to the power of 6 and get 64.
64+(−3)
2
Calculate −3 to the power of 2 and get 9.
64+9

The real question you need to solve is "Is 1/4 greater than, equal, or less than 15/100?" At first glance it's hard to determine how they relate to each other. So first make both fractions use the same denominator. The easiest way to do this is multiply both the numerator and denominator of each fraction by the denominator of the other fraction. So
1/4 * 100/100 = 100/400
and
15/100 * 4/4 = 60/400
Now ask yourself "Is 100/400 greater than, equal, or less than 60/400?" and the answer is pretty obvious. 100/400 > 60/400. So the answer is ">".</span>
Notice the picture
we have, the opposite side
the angle
and we want the hypotenuse
so recall your SOH CAH TOA

which one has all that? low and behold, is Ms Sine,
so let's bother Ms Sine

make sure your calculator is in Degree mode, since the angle here is in degrees, as opposed to Radian mode
Answer:
degrees.
Step-by-step explanation:
Line ABC is a straight line, and the angle on a straight line is always 180 degrees.
Since ABD + DBC = ABC, we know that 

Divide both sides by 9:

DBC is
degrees.
