Answer:
d = 41
Step-by-step explanation:
if the two lines are parallel, then 113 and 2x-5 are supplementary, which means that they add up to 180.
So:
113 + 2x - 5 = 180 =>
2x = 72
x = 36
Next step, we have three angles in the triangle that should add up to 180:
2x-5 + 2x + d = 180 with x=36
d = 180 - 139 = 41
so the angles are 72, 67 and 41
Given:
The two points C(2,-1) and D(5,3) on a coordinate plane.
To find:
The distance from C to D.
Solution:
The distance between two points is defined by the distance formula.
The two points are C(2,-1) and D(5,3). Using the distance formula, we get
On further simplification, we get
The distance from point C to D is 5 units. Therefore, the correct option is A.
The answer is B. 7 times a number plus 4 would be 7n +4.
