Answer:
m∠D=14
Step-by-step explanation:
∠C and ∠D are vertical angles with m∠C=−x+26 and m∠D=2x−10
Vertical angles are equal. So equate the angles C and d . Solve for x
m∠C=m∠D
[tex]-x+26=2x-10[/tex]
Subtract 2x from both sides
[tex]-3x+26=-10[/tex]
Subtract 26 from both sides
[tex]-3x=-36[/tex]
Divide both sides by -3
x=12
m∠D=2x−10
Substitute 12 for x
m∠D=2(12)−10=24-10= 14
