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>

The Ration of length 2.0 meters to the length 1.2 meters = 5 : 3
Step-by-step explanation:
The given two length are 2.0 m and 1.2 m
Length L1 = 2.0 m And
Length L2 = 1.2 m
SO, The ratio of L1 : L2 =
Or, The ratio of L1 : L2 =
∴ The ratio of L1 : L2 =
Hence The ratio of L1 : L2 is 5 : 3 Answer
