Answer:
x = 2
Step-by-step explanation:
2(x+1)=3x
2x+2=3x
2x - 3x=-2
-x=-2
57 degrees because 180-123= 57 degrees
Answer:
x = 4.
Step-by-step explanation:
I am assuming that you want to find the values of x and that WXYZ is a parallelogram.
In a parallelogram opposite sides are equal, therefore:
11x + 1 = 19x - 31
1 + 31 = 19x - 11x
32 = 8x
x = 32/8 = 4.
72 + 12 = 84 stickers
ignore “she put 9 stickers on each page” because the question asked how many stickers she had total not how many on each page
We are asked to find the principal value of
cos ⁻¹ (0.69)
which is just the least positive angle
cos ⁻¹ (0.69) = 46.37°
Other values of
cos ⁻¹ (0.69) is
46.37° - 180° n
where n is a whole number
