Answer:
parallel line slop2 = -5/4
perpendicular line slope = 4/5
Step-by-step explanation:
If 2 lines are parallel, they will have equal slopes.
Therefore, the slope of a line parallel to y = 1/4 - 5/4 x will be -5/4
If 2 lines are perpendicular, their slopes are negative reciprocals of each other. So the slope of the perpendicular line = -1 ÷ -5/4 = 4/5
Answer:
20.27
Step-by-step explanation:
Answer:
Here's how I would do it.
Step-by-step explanation:
If two triangles are similar, corresponding sides are in the same ratio.
We know the measures of b and a, so we can calculate the ratio b/a.
d and b are in the same ratio, so
We know the measures of c, b, and a, so we can calculate the value of d.
Answer:
a
