Answer:
x = 26
Step-by-step explanation:
sin x =4/9
Take the inverse sin of each side
sin ^-1 (sin x) = sin^-1(4/9)
x=26.38779
To the nearest degree
x = 26
Answer:
61
Step-by-step explanation:
PS is a midsegment of the triangle, so is half the length of the parallel base segment.
2PS = QR
2(x -16) = x +29 . . . . . substitute given expressions
2x -32 = x +29 . . . . . eliminate parentheses
x = 61 . . . . . . . . . . . . add 32-x
Answer: the answer is a 12
Step-by-step explanation:
Answer:
a = 4
b = -11
Step-by-step explanation:
use the complete the square method:
we completed the square of x^2 + 8x + ... which is x^2 + 8x + 16 using (x+4)^2
we added 16 to both sides because whatever you do to one side, you have to do to the other:
