okay so
117° + angle a = 180° (supplementary angle)
angle a = 180 - 117
= 63°
then angle a + angle b + 81° = 180° ( angle sum property)
so... 63° + angle b + 81° = 180
144 + angle b = 180°
angle b = 180 - 144
= 36°
hope this helps.

Step-by-step explanation:
cos62˚ ≈ 0.469
0.469 x 12 = 5.628
R=i/pt
R=1680/3000*8=1,680÷24,000
=0.07*100=7%
The answer is D: 5p = 120
Answer:
