Answer:
The value of x= 7 and that of Angle A= 157°
Step-by-step explanation:
(x+16)° = (4x-5)° [Vertically opposite angles]
3x= 21
x= 7
Now, A + (4x-5)° = 180° [Linear pair]
A + [4(7)-5] = 180°
A + 23 = 180°
A = 180° - 23
A = 157°

Π/12 is half of π/6, which is 30 degree
tan(α/2)=(1-cosα)/sinα)
plug in the values: tan(π/12)=(1-cosπ/6)/sin(π/6)=(1-√3/2)/(1/2)=2-√3

<u>Equation:</u>
- cos 28 = 11/x
- x = 11/ cos 28
- x = 12.5 (rounded)
Answer:
it would be -90⁰ because its clockwise its the opposite direction
