Answer:
Add the two angles: 43° + 47° = 90°.
Step-by-step explanation:
A right triangle has an angle that equals 90°. Complementary angles equal 90°. Therefore, if you add these two angles, you will know whether or not △ABC is a right triangle. Triangle △ABC is broken up into two angles, m∠ABD and m∠DBC. When the measures m∠ABD and m∠DBC are added together, they equal 90°, and thus, form a complementary angle.

XZ = square root (16^3 + 63^2)
XZ = square root (256 + 3969)
XZ = square root (4225)
XZ = 65
sin(Z) = 16 / 65
answer is A. 16/65
