Answer:

x=21

Step-by-step explanation:

Following the vertical angles, we can assume that the equation that has x and 87 are equal to each other. From then, you set them equal to each other and solve for x.

87=4x+3

84=4x subtract 3 from both sides

21=x divide by 4 to get the x alone on both sides

Answer:

x = 3.7

Step-by-step explanation:

By applying sine ratio for the given angle B,

sin(39°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

sin(39°) = $\frac{AD}{AB}$

0.6293 = $\frac{AD}{7}$

AD = 4.41

By applying tangent ratio for the given angle C,

tan(50°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

1.19 = $\frac{AD}{x}$

1.19 = $\frac{4.41}{x}$

x = 3.7
