Answer:
x = 68º
Step-by-step explanation:
This trapezoid is a quadrilateral. All degrees in a quadrilateral have to add up to 360º.
76º + 135º + 81º + xº = 360º
292º + xº = 360º
xº = 360º - 292º
xº = 68º
Answer:
27, 200, 200, 217, 227, 227, 712
Step-by-step explanation:
Kate: Please, for clarity, use " ^ " to denote exponentiation: 2x^2 + x − 4 = 0
And please include the instructions.
2x^2 + x − 4 = 0 can be re-written: 2(x^2 + (1/2)x - 2) = 0
Dividing both sides by 2 results in x^2 + (1/2)x - 2 = 0
Let's "complete the square:" x^2 + (1/2)x + (1/4)^2 - (1/4)^2 = 0
Then (x+(1/4))^2 = (1/4)^2
Taking the sqrt of both sides: x+1/4 = plus or minus 1/4
Solving for x: x = -1/4 plus or minus 1/4
Solving for x (continued): x = 0 and x = -1/2
