A line passes through (-1, 7) and (2,10) which equation is the equation of the line? -x y=12 -x y=8 -3x y=16 -3x y=4

notka56 [123]

Equation of a line through two points is given by y - y1 = ((y2 - y1)/(x2 - x1))(x - x1)
y - 7 = ((10 - 7)/(2 - (-1)))(x - (-1))
y - 7 = (3/(2 + 1))(x + 1)
y - 7 = 3/3 (x + 1)
y - 7 = x + 1
-x + y = 1 + 7
-x + y = 8

NO LINKS!!! Find the measurement indicated. Round your answer to the nearest tenth.

My name is Ann [436]

Answer:

Solutions given;

Using cosine rule

b²=a²+c²-2*a*c*cos B°

b²=15²+8²-2*15*8*cos39

b²=102.48

b= $\sqrt{102.48}$

b=10.12

b=10.1

Using sine rule

$\frac{sin A}{BC} = \frac{sin B}{AC} =\frac{sin C}{AB}$

$\frac{sin 29°}{15} =\frac{sin C}{8}$

Doing criss cross multiplication

Sin C= $\frac{sin 29°}{15} ×8$

m<C=Sin -¹(0.29)

m<C=14.98

m<C=15°is a required answer.
