∠axc is a straight angle and ∠axd measures 90°. which statement correctly describes ∠dxc?

Solution:

As given ∠AXC is a straight angle and ∠AXD measures 90°.

Measure of a straight angle =180°

∠AXD = 90°

∠AXD+∠DXC=180°[ ∴∠AXC is a straight angle]

→90° +∠DXC=180°

→∠DXC=180°-90°

→ ∠DXC=90°

∠DXC  measures right angle i.e having measure 90°.

i would say c is the best answer, hope it's right!

good luck! =)
