A. Find and explain the error in the work shown.
1 answer:
Well, first they're assuming that the m<ABC = 90
The value of m<ABC is not given, so they aren't allowed to make up values based on the way the picture looks.
It is given that BD bisects <ABC, which means it splits the angle evenly..
Giving this equation: (x-5) = (2x-6)
Solving for x
-5 + 6 = 2x - x
1 = x

Answer:
=0.4
Step-by-step explanation:
1/3= 0.33
5/6=0.83
Then: 0.33/0.83 = 0.4
You can also do 6/15 which results from (1*6)=6 and (3*5)=15

Answer:
No, because substituting the given ordered pair doesn't yields two true expressions
Step-by-step explanation:
5x + y = 8
5 + 3 = 8 so thats correct
x + 2y = 5
1 + 6 =7, not 5
so only 1 is correct
Answer:
angle of depression = 59.04 degrees
Step-by-step explanation:
tangent X = 30/50
tangent X = 0.6
x = 30.96 degrees
90-30.96 = 50.04 degrees
