Answer:
11.64
Step-by-step explanation:
8.24+3.4=11.64
When you say two angles are complementary, they add up to 90 degrees.
Since two angles are the ratio 2:7, you can represent the smaller angle as 2x and the larger as 7x.
add them up as 2x+7x=90
2x+7x=9x 90/9x=10x
the angles are 2x=20 degrees and 7x=70 degrees
so the smaller angle is 20 degrees
Answer:

Step-by-step explanation:
The slope of
is:
The negative reciprocal of that slope is:
So the perpendicular line will have a slope of
:
And now put in the point
:
And that answer is OK, but let's also put it in
form:
1: 0.5 and 50%
2: .2 and 20%
3: .75 and 75%
10: (1/10) and 10%
11: (3/5) and 60%
12: (1/4) and 25%
