What is the value of x in the figure shown?
A quadrilateral is shown with the measurements of four angles shown. The first angle measures 65 degree sign. The second angle measures 123 degree sign. The third angle measures 87 degree sign. The fourth angle measures x degree sign.

85°

Step-by-step explanation:

Sum of angles in a Quadrilateral = 360°

Angles include : 65°, 123°, 87° and x°

65 + 123 + 87 + x = 360

x + 275 = 360

x = 360 - 275

x = 85°

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

60.9774

step-by-step explanation:
