Answer:
90.51 (rounded to the nearest hundredth)
Step-by-step explanation:
We can use trigonometry to figure this out
sin = opposite side / hypothenuse
The 45° angle's opposite side is a leg of the triangle
sin 45 = leg / 128
sin 45 * 128 = (leg / 128 ) * 128
0.7071 * 128 = leg
90.51 = leg
A quadrilateral simply means a shape that has 4 straight sides. Imagine a square or rectangle - they are both quadrilaterals.
You answer is 12 because that is where on the graph it is the most constant
Answer:
x =42
Step-by-step explanation:
x and 138 are same side interior angles. Same side interior angles are supplementary when the lines are parallel
x+138 = 180
x = 180-138
x =42
