Answers:
Part A: The value of x must be 0
Part B: The value of x can be any real number
----------------------------------------------------------------
Explanation:
Part A) We have the equation (7^2)^x = 1 which simplifies to 7^(2x) = 1. The only way to get the left side equal to the right side is to have the exponent of 2x equal zero. If 2x = 0, then x = 0. So that's why x = 0 is the only solution here.
--------------
Part B) Similar to part A above, but the exponent is slightly different now. We have (7^0)^x = 1 which turns into 7^(0*x) = 1. The exponent 0*x is really 0 no matter what x is. We can plug in any real number we want for x and the left side will always be 1. This is why the solution set to this equation is the set of all real numbers.
To solve this
problem, we must remember that the sum of interior angle of a polygon is:
Sum of
interior angles = (n – 2) * 180˚
So, we can say
that:
Sum of
interior angles = angle A + angle B + angle C + angle D = (4 – 2) * 180˚
Where,
angle C + angle
D = 110 + 70 = 180˚
Therefore
substituting this value:
angle A + angle
B + 180˚ = 2 * 108˚
angle A + angle
B = 360˚ - 180˚
angle A + angle
B = 180˚ (answer)
Hence we can
also conclude that,
<span>angle A + angle
B = angle C + angle D</span>
