Answer:

6/20 and 9/30

Step-by-step explanation:

Any fraction that can be simplified to 3/10 by dividing the numerator and the denominator is considered equivalent. If you look at the fractions above 6/20 is literally the same thing as 3/10 but I just multiplied the 3 and 10 times 2. As long as you multiply/divide both the numerator and the denominator by the same number the answer you get should be equivalent.

Given m∠B = 62, m∠C = 54 and line AD bisects ∠BAC, find m∠ADB

insens350 [35]

THE ANSWER IS: 86 degrees

first find the measure of angle a: since all angles of a triangle add up to 180, add the measures of angle b and angle c then subtract it from 180 to get angle a: 62+54=116, 180-116=64

since we know line AD bisects angle a, we can divide 64 degrees by 2 to find angle BAD: which is 32 degrees

then subtract both 62 and 32 from 180 to get 86 degrees for angle ADB
