Answer:
7.7ft
Step-by-step explanation:
The trigonometric ratios of the right triangle with the given value tan A = 9 / 40 are
sin A = 9 / 41
cos A = 40 / 41
<h3>Trigonometric ratios</h3>
Trigonometric ratios are used to solve for the sides and angles of a right angle triangle.
Therefore,
sin A = opposite / hypotenuse
cos A = adjacent / hypotenuse
tan A = opposite / adjacent
Using Pythagoras theorem, let find the hypotenuse side
c² = 40² + 9²
c = √1681
c = 41
Therefore,
sin A = 9 / 41
cos A = 40 / 41

Answer:
isosceles triangle
Step-by-step explanation:
line CB is the transversal for the two parallel lines, so angle CBA and angle BCE are the same.
since a straight line is 180 degrees, we can solve for angle BCA by subtracting the other angles on the line from 180
180-80-50 = 50
since triangles have 180 degrees, we can solve for the last angle by subtracting the angles we already know from 180
180-80-50
two of the angles are the same, making this an isosceles triangle
