Find the measure of <_B. (Show your work if possible).

We know that exterior angle of a triangle is equal to the sum of two opposite interior angles

Step-by-step explanation:

Here

<A = 4y

<B = 3y + 14°

<BCD = 119°

Now

<BCD = <A + <B ( Exterior angle of a triangle is equal to the sum of two opposite interior angle)

119° = 4y + 3y + 14°

119°- 14° = 7y

105° = 7y

Therefore y = 15°

Now < B = 3y + 14°= 3*15° + 14°=59°

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
