Answer:
Step-by-step explanation:
In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.
Using the formula above,
Substitute the value of m into the equation:
To find the value of b, substitute a pair of coordinates into the equation.
When x= 2, y= 5,
5= 3 +b
b= 5 -3
b= 2
Thus, the equation of the line is .
Answer:
Step-by-step explanation:
3. Use Cosine law to find the length of the unknown side (PR)
q² = p² + r² - 2prCos Q
q is the opposite side of ∠Q;
p is the opposite side of ∠P; p = 33
r is the opposite sides of ∠R ; r = 67
q² = 33² + 67² - 2* 33*67 Cos 19°
= 1089 + 4489 - 4422 * 0.95
= 1089 + 4489 - 4200.9
= 1377.1
q = √1377.1
q = 37.1
PR = 37.1
To find the angle use law of sin
Sin P = 0.3
P = 17.5°
∠R = 180 - (19 + 17.5)
= 143.5°
