Sine, cosine, and tangent to calculate the height of the buildings in the diagram below.
1 answer:
Answer: Around 68.0858 m
Step-by-step explanation:
- Set the height of 37°-53°-90° triangle as x
- Set the height of 50°-40°-90° triangle as y
- The horizontal side both triangles share = 35
To find x To find y
To find the height of the building, add the x-value and y-value:

Answer:
y = 10/9x + 9
Step-by-step explanation:
To write the equation in its slope-intercept form, y = mx + b, we need to find the slope (m) of the line and its y-intercept (b).
Given the points (0, 9) and (9, 19), we can solve for the slope of the line using the following formula:
Let (x1, y1) = (0, 9)
and (x2, y2) = (9, 19)
Substitute these values on the formula:
Therefore, the slope (<em>m </em>) = 10/9.
Next, the <u>y-intercept</u> is the point on the graph where it crosses the y-axis, and has the coordinates, (0, <em>b </em>). It is also the value of the y when x = 0.
One of the given points is the y-intercept of the line, given by (0, 9). The y-coordinate, 9, is the value of b.
Therefore, the linear equation in slope-intercept form is: y = 10/9x + 9
