Answer: 180 i believe
Step-by-step explanation:
Step by step:
y^2- 14y+48=0
y^2-14y=-48
y^2-14y+49=-48+49
(y-7)^2=1
Answer: y=7+-1
It looks like the length of a and b should be the same. You can use the Pythagorean theorem (only works with right triangles):
a² + b² = c² (c is the hypotenuse or the longest side of the triangle, a and b are the other side lengths of the triangle)
a² + (4)² = (5)²
a² + 16 = 25
a² = 9
a = 3
a and b have a length of 3
Yo sup??
the angle is in 3rd quadrant.
we can say that
sin(90+150)
=sin(180+60)
=-sin(60)
=-3^(1/2)/2
Hence the correct answer is option A
Hope this helps
