8-33.

Use the geometric relationships in the diagrams below to solve for $x$. Homework Help ✎

1. This is an isosceles triangle. Are there any special qualities about isosceles triangles that you know?

Base angles in an isosceles triangles are congruent.

$180º − 82º = 98º$ then take
$98º ÷ 2 = 49$°.
Both base angles will be $49º$.

$x = 49º$

1. Both base angles are $71º$. See part (a) for help.
