Use the intersecting chords theorem: the labeled angle (WVZ) between the given chords has measure that is the average of the two arcs the chords intercept (WZ and XY):

$81^\circ=\dfrac{m\widehat{XY}+52^\circ}2\implies m\widehat{XY}=110^\circ$

Decide whether ABC is a right angle triangle

The triangle is not a right angle

AC = 22 - 8 - 5 = 9
AC² = AB² + BC²
81 = 64 + 25
81 isn't equal to 89, the triangle is not a right angle

You'll want to first simplify the expression $(2t-8)- \frac{1}{2} (9-4t)+ \frac{5}{2}}$ .

To do that, first distribute the $- \frac{1}{2}$ :

$(2t-8)- \frac{1}{2} (9-4t)+ \frac{5}{2}}$
$2t-8- \frac{9}{2} +2x+ \frac{5}{2}$

From there, you may just combine like terms:

$2t-8- \frac{9}{2} +2t+ \frac{5}{2}$
$4t-8- \frac{9}{2} + \frac{5}{2}$
$4t-8- \frac{4}{2}$
$4t-8-2$
$4t-10$

Answer:
D. 4t - 10
