Activity Question 1 When designing a truss, a truss builder might know the base angle measurement and the length of the tie beam

needed. The next step is to compute the height of the king post. Let's take a look at some right triangles to see whether knowing the measure of an acute angle of a right triangle and the length of one of the sides is enough to find the lengths of the other two sides. Part A What is the measure of ∠BAC?

Write an equation of the line that passes through point P and is parallel to the line with the given equation:
Anna11 [10]

Answer:

y = 2x -1

Step-by-step explanation:

The line  y = 2x - 6 is in slope-intercept form, so the slope = 2.  The line you are looking for is parallel, hence also has a slope of 2.

Now, use the point-slope form of a line y - y_{1}  =  m(x - x_{1} )

y - 5 = 2(x - 3)

y - 5 = 2x - 6

y = 2x -1
