T +7 is Tim's age in 7 years
three times what it was 19 years ago = 3(t-19)

so equation should be:
t + 7 = 3(t - 19)

Answer:

$^\frown_{AB}=11.16m$

Step-by-step explanation:

The given circle has radius 8m and a central angle of $80\degree$ .

We want to find the length of arc AB.

Recall that the length of an arc is given by:

$l=\frac{\theta}{360\degree}\times 2\pi r$

where $\theta=80\degree$ is the central angle and $r=8m$ is the radius.

$^\frown_{AB}=\frac{80}{360\degree}\times 2*3.14*8$

This simplifies to:

$^\frown_{AB}=11.16m$
