We are given with two angles in which the side opposite to one angle is named while the other one is unknown. To find the unknown, we use sine law. The formula goes sin 29.16 / 3 = sin 54.33 / b; <span>b is equal to 5.0. The answer is D then </span>

Equation of a straight line (see attached)
Viefleur [7K]

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2,3)

m = \frac{3-7}{2-4} = \frac{-4}{-2} = 2 , thus

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 3), then

3 = 4 + c ⇒ c = 3 - 4 = - 1

y = 2x - 1 ← equation of line

The one with the word bank is in this order, right angle, acute angle, straight angle and then obtuse then you try to guess an estimate a right angle is always a 90 degree angle and a straight angle is always 180 degrees the given part of the angle would be subtracted by 180 for example 180-130 which means X= 50 degrees
