Answer: 42/12 or 3.5
Step-by-step explanation:
5(6)/3(-4)= -30/12
-30/12 + 6 or -30/12 + 72/12 = 42/12 or 3.5
Answer:
15) ∠BCD = 1/2 short arc BC = (360° -260°)/2 = 50° (C)
16) ∠K is supplementary to short arc JL = 180° -120° = 60° (C)
17) ∠V is half the difference of long arc TW and short arc UW.
.. (198° - UW)/2 = 69°
.. 198° -138° = UW = 60° (C)
18) ∠L is supplementary to short arc KM
.. KM = 180° -66° = 114° (C)

Triangle ABC is an isosceles triangle. This means that base angles A and C are the same measure.
Triangle CDE is also isosceles. This means that angles C and D are the same measure.
The hatch marks shown in both triangles clearly indicate this fact of geometry.
So, if angle C is 40 degrees, C and D must be 70 degrees each because the sum of the angles in a triangle is 180 degrees.
Angle C = 70 degrees.
