Solve for x - PLEASE NEED HELP, this is my 3rd time posting it.

Step-by-step explanation:

First, remember that the maximum degree of an angle totals 360°.

Since we already have 294°, this means that what is left must total .

Therefore, this means that our two smaller angles must equal 66°. So:

Solve for x. Add on the left:

Subtract 8 from both sides. Therefore, the value of x is:

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
