When designing a truss, a truss builder might know the base angle measurement and the lengur UI te te verleeu. 11 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.

You will use GeoGebra to explore the trigonometric ratios when an acute angle is fixed for a given right triangle. Go to trigonometric ratios

and complete each step below. The right triangle represents half of a king post truss. If you need help, follow these instructions for using

entering that problem on the tube might get you an answer

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
