- Is JM an Altitude of triangle JAM?
- What is another altitude?
- At what point all three altitudes meet?
- Where all the three perpendicular bisectors meet?
- Does theorem 10-2 supports (d)?

Explanation of Solution
Given:
JAM is a right-
Calculation:
a.
Line JM is perpendicular to the side MA.
Therefore, the line JM is an altitude of the triangle JAM from the vertex J.
b.
By observing the given figure:
Line AM is also an altitude of this triangle from the vertex A.
c.
From the point M draw two arcs on the line JA with equal lengths.
From X and Y draw other two arcs and mark their intersection as a point Z and join MZ.
MXZ and JA intersect at point D.
MD is an altitude of triangle JAM that contains the vertex M.
d.
The perpendicular bisectors of a right-angled triangle meet at a point on the hypotenuse of this triangle as shown below:
e.
In the given figure,
X is equidistant from the vertices M, J, A. Hence, the theorem 10-2 supports (d).

- Can someone help me with this please?arrow_forwardMariela is in her classroom and looking out of a window at a tree, which is 20 feet away. Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward1arrow_forward
