Answer:
2.2
Step-by-step explanation:
To find a, you use a formula called the law of cosines:
The law of cosines tells us:
a^2 = b^2 + c^2 - 2bc cosA
So lets plug in the values:
a^2 = 4^2 + 3^2 -2(4)(3)cos(32)
a^2 = 25-24cos32
a^2 is roughly equal to 4.97
therefore a roughly equal to 2.2
Answer:
Slope is 1/3
y-intercept = -4
Step-by-step explanation:
The equation;
y = 1/3x - 4 is an equation of a straight line on cartesian plane.
The slope is just derived from 1/3x and its 1/3
The y intercept is when x = 0 and its -4
