Angles in a parallelogram have to equal 360.
Let x represent the measurement of the unknown angle.
2(55) + 2x = 360
110 + 2x = 360
2x = 250
x = 125
125 degrees
3x=90 2x=50
And the last one is 40
Answer:
7x² + 5x
Dtep-by-step explanation:
(9x² + 8x) - (2x² + 3x)
9x² + 8x - 2x²- 3x
7x² + 5x
The product of two radicals is equal to the radicand. The square root deletes itself.
So the result is y^3
The temperature would be (21.5 + 6.25) which is 27.75
