From the given figure there are 2 parallel lines intersected by a transversal

Then they formed a pair of exterior alternate angles (80 degrees and 4x)

Since the exterior alternate angles are equal in measures, then

4x=80^{\circ}

Divide both sides by 4 to find x

\begin{gathered} \frac{4x}{4}=\frac{80}{4} \\ x=20 \end{gathered}

The value of x is 20

What is the value of D to the nearest tenth ?
Naily [24]
<span> If two secants intersect from a point outside of the circle, then you can use formula:

26(26 + d) = 22(22 + 40)
676 + 26d = 22 * 62
26d = 1364 - 676
26d = 688
d = 688/26
d = 26.5   </span>←  to the nearest tenth
