In the accompanying diagram of ABC ca is extended to D, m∠ABC = 70 and m∠BCA =50 Find m∠DAB
1 answer:
Answer:
<em>120 degrees</em>
Step-by-step explanation:
Find the diagram attached.
From the diagram;
Interior angles are m∠BCA and m∠ABC
Exterior angle is m∠DAB
The sum of interior angle of the triangle is equal to exterior
m∠BCA +m∠ABC =m∠DAB
Given
m∠ABC = 70
m∠BCA =50
m∠DAB = 70 + 50
m∠DAB = 120 degrees
<em>Hence the measure of m∠DAB is 120 degrees</em>

Hey!
We know that if we see a number that apparently doesn't have a denominator, we can plug a "1" as a denominator because it's a whole number, for example, we could write.
Finding the inverse would be taking the reciprocal of it, that implies switching the fractions, the signs would change too, so, this would mean that the reciprocal of
would be,
Using Math, we can verify this is correct. To do that, we would have to use exponents.
