A quadrilateral has angles that measure 56°, 97°, and 136°.What is the measure of the fourth angle?

Answers

Answer 1

Answer: Angles of a quadrilateral add up to 360 degrees. Thus;
360-(56+97+136)
=71°

Answer 2

Answer: The sum of the interior angles can be represented by:
180(n-2)
180 x 2 = 360
Therefore, the sum of the angles must be 360.

56 + 97 + 136 = 289
360 - 289 = 71°

You buy 5 tickets to a concert for you and your friends. You pay $170, including a $20 service charge. How much does one ticket cost?

Answers

30 is your answer. (170 -20=160/5=30)

You would subtract $20 from $170 and divide the $150 by five so each ticket would cost $30

Step-by-step explanation:

Verify csc^4 - cot^4= 2cot^2 +1

Answers

you can factor the left side of the equation to

(csc^2 + cot^2)(csc^2 - cot^2)

then, since cot^2 + 1 = csc^2, you can replace the csc^2 in the left parentheses with cot^2 + 1, and the cot^2 in the right parentheses with csc^2 - 1 (which equals cot^2)

then, youll end up with

(cot^2 + 1 - cot^2)(csc^2 + csc^2 - 1)

combine like terms, and the left parentheses becomes 1 (cot^2 - cot^2 = 0), and the right parentheses becomes 2csc^2 - 1.

1(2csc^2 - 1) = 2csc^2 - 1
