Answer:

Add 36. The factored form is (x+6)^2.

Step-by-step explanation:

A perfect square is a trinomial that factors into the form (x+a)^2. To find the value to add to it divide 20 by 2 and square it.

12/2 = 6

6*6 = 36

This means c=36. The factored form is (x+6)^2.

Answer:

27°

Step-by-step explanation:

Step 1:

∠A + ∠C + ∠D = 180°     Sum of a Δ

Step 2:

3x - 10 + 45 + 2x + 10 = 180        Input all values

Step 3:

5x + 45° = 180°     Combine Like Terms

Step 4:

5x = 135°        Subtract 45° on both sides

Step 5:

x = 135° ÷ 5       Divide

Answer:

x = 27°
