Find the measure of angle b
2 answers:
Answer:
b = 65 degrees
Step-by-step explanation:
As we can see, the line that angle b and 115 deg correspond to is a straight line. A straight line <em>always</em> measures at 180 deg.
Because of this principle, we know that:
We can simplify this one variable equation now:
Now solve:
And this makes sense. Just by eyeballing the angle, we can see that it is under 90 degrees.
So, b = 65 degrees
Answer:
<h2><u><em>
65°</em></u></h2>
Step-by-step explanation:
angles are on a straight line = sum of 180°, to find the value of "b" subtract the known angle (115°) from 180°
180 - 115 = <u><em>65°</em></u>
