Answer:
cos 60° = 1/2
SohCahToa
- Sin = opposite/hypotenuse
- Cos = adjacent/hypotenuse
- Tan = opposite/adjacent
sin 60° = opposite / hypotenuse
sin 60° = √3 / 2
The bottom side = √3, the hypotenuse = 2
To find the right side's value, you use Pythagorean's Theorem
- a² + b² = c²
- a² + (√3)² = 2²
- a² + 3 = 4
- a² = 4 - 3
- a² = 1
- a = 1
cos 60° = adjacent/hypotenuse
cos 60° = 1 / 2
Answer:
sin 60 = √3/2
means perpendicular (p)= √3
and
base (h)=2
find base(b)
using pythagoras theorem
h²=p²+b²
than base (b) will be 1
now
cos 60 =b/h
=1/2

Answer:
y=(5/4)x-5/4
Step-by-step explanation:
First we need to find the slope:
=
=5/4
The SLops is 5/4
point-slope forum is
y=(5/4)x-5/4
(i think)
X° = 180° - 160°
= 20°
x = 20
