In the following triangle, find the values of the angles B and B1, which are the best approximations to the solutions to this ambiguous case. ​

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

part a: 1.08

part b: 27.59

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
