Answer:
C) 120 degrees
Step-by-step explanation:
m<A + m<B + m<C = 180
45 + m<B + 15 = 180
m<B + 60 = 180
m<B = 120
Answer:
the shorter leg is 10 meters, longer leg is 24 meters and the hypotenuse is 26 meters
Angle 2 = 22 degrees (that line is dividing that angle into 1 & 2 equivalently)
Angle 3 = 90 degrees.
Answer:
X=22
Step-by-step explanation:
Answer:
Raising something to a negative exponent is just taking the reciprocal of the amount.
Step-by-step explanation:
Let's assume that you wanted to know what 
is.
To find it, you would take the reciprocal of the x amount. So becomes 
.
This works because of the nature of exponents. Exponents represent the number of times you are multiplying a value by itself. So 
would be equal to a · a · a. To increase the exponent, you increase the number of times the value is multiplied by itself: To increase to 
, you would have to multiply a with two more times (a · a · a · a · a). To decrease the exponent, you must divide the value by itself. So to decrease to 
, you would have to divide by a 3 times.
If the exponent is 0, the value is equal to 1. But you can still decrease the exponent into negative numbers. You just divide 1 by a the desired amount of times: 
means that you are dividing 1 by a 3 times.
Hope this helps.
