Answer: 104
Step-by-step explanation:
180-38-38=104
∠ ABD = 5(2X+1)
∠ DBC = 3X+6
∠ EBC = Y +135/2
∠ ABD and ∠ DBC are linear pairs
∴ ∠ ABD +∠ DBC = 180
∴ 5(2X+1) + 3X+6 =180
solve for x
∴ x = 13
∴∠ ABD = 5(2X+1) = 5(2*13+1) = 135
∠ DBC = 3x+6 = 3*13+6 = 45
∠ ABD and ∠ EBC are vertical angles
∴ ∠ ABD = ∠ EBC = 135
∴ y +135/2 = 135
∴ y = 135/2

C.) x=13
E.)measure of angle EBC =135
F.) angle DBC and angle EBC are linear pairs

The coefficient of a variable is the number that comes from before the variable. In this case, the coefficient of x is 3 a assuming a is constant. T<span>he coefficient of x^2 is -11 while the constant of the expression above is 20 a. Answer to this problem is 3 a.</span>
Answer
Law of Sines
Step-by-step explanation:
If you have all three side lengths, you can use law of sines.
side length a/sin of angle a=side length b/sin of angle b=side length c/sin of angle c
not sure if that makes sense but look up the law of sines!
Angle G is common to both of the triangles.
