I don’t know how to solve for Q.
Naya [18.7K]

Answer:

  ∠Q = 75°

Step-by-step explanation:

Start by recognizing that the triangle is isosceles (the long sides are marked as being equal-length). That means angles Q and R have the same measure.

Next, you use the fact that the sum of angles is 180° to write an equation.

  ∠R +∠P +∠Q = 180°

  (2x +15)° +x° +(2x +15)° = 180° . . . . substitute the known values

  5x +30 = 180 . . . . . . . . . . . . . . . . divide by °, collect terms

  5x = 150 . . . . . . . . subtract 30

  x = 30 . . . . . . . divide by 5

Then angle Q is ...

  ∠Q = (2x +15)° = (2×30 +15)°

  ∠Q = 75°

12 pts? Harris and Annabelle are 200 feet apart, and they are standing on opposite sides of a tree. The angles of elevation from
Sergio [31]
If we are to connect the root of the tree to a person to the top of the tree, we form two right triangles. If we let x and and 200 - x be the distance of Harris and Annabelle from the tree, respectively and h be the height, we form the trigonometric functions,
                                       tan 30° = h/x
                                       tan 35° = h/(200 - x)
The values of h and x in the equations are 63.28 ft and 109.62 ft, respectively. Thus, the answer to this item is approximately 63.28 ft.
