Answer:
x = 31.12
Step-by-step explanation:
First find the base (hypotenuse) of the smaller triangle (the isosceles triangle): Its three sides are 11, 11 and b. b can be found using the Pythagorean Theorem: b^2 = 11^2 + 11^2 = 242. Then b = √242, or b = approximately 15.56.
b (which is approximately 15.56) is the shorter leg of the large (right) triangle. The trig function needed to solve for x is the cosine:
adjacent side
cos 60 degrees = ----------------------
hypotenuse,
15.56
which becomes (1/2) = ------------
x
Solving this for x, we get: x = 2(15.56) = 31.12
Answer:
![y = -\frac{1}{2}x + 4](https://tex.z-dn.net/?f=%20y%20%3D%20-%5Cfrac%7B1%7D%7B2%7Dx%20%2B%204%20)
Step-by-step explanation:
The equation of the line can be written in slope-intercept form, as y = mx + b.
We need to find the slope (m) and the y-intercept (b) of the line, then plug their values into the slope-intercept equation, to find the equation of the line shown.
y-intercept (b) = the point where the line intercepts the y-axis = 4
Using two points on the line, say, (0, 4) and (2, 3):
![slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 4}{2 - 0} = \frac{-1}{2} = -\frac{1}{2}](https://tex.z-dn.net/?f=%20slope%20%28m%29%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20%3D%20%5Cfrac%7B3%20-%204%7D%7B2%20-%200%7D%20%3D%20%5Cfrac%7B-1%7D%7B2%7D%20%3D%20-%5Cfrac%7B1%7D%7B2%7D%20)
m = -½.
Substitute m = -½, and b = 4 into y = mx + b.
The equation of the line would be:
![y = -\frac{1}{2}x + 4](https://tex.z-dn.net/?f=%20y%20%3D%20-%5Cfrac%7B1%7D%7B2%7Dx%20%2B%204%20)
