What is the measure of the vertex angle of an isosceles triangle if the base angles measure 56 degrees?
If each base angle is 56°, then the vertex angle is 68°.If both base angles combined total 56°, then the vertex angle is 124°.
If pyramid base edge is 3cm what is slant height?
Depends on the angle between the side and the base. The smaller the angle the larger the height.
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 58?
One of the base angle is 58 deg so the other base angle is 58 deg. Sum of all three angles is 180 deg so the third angle (the vertex angle) is 180 - 58 - 58 = 64 degrees.
Is it possible for a segment to be a perpendicular bisector angle bisector median and altitude of a triangle?
Yes. If you have an isosceles triangle standing up on the unequal side, thenthe line segment from the top vertex perpendicular to the base is all of these.
The exterior angle of a base angle in an isosceles triangle is 100 degrees What is the measure of the vertex angle?
20 degrees
What is the relationship between the angle of elevation and the highest point?
If the base of the elevation is at a distance d from the observer, then the highest point is at a height = d*tan(angle of elevation)
A building is 120 feet high. at a certain distance away from the building. an observer notices the angle of elevation to the top of the building is 41 degrees. how far is the observer from the base of the building?

How do you find angle of elevation when given hypotenuse and a base?
Given the hypotenuse and the base ...-- divide the (base) by the (hypotenuse); get a number less than '1'.-- the number is the 'cosine' of the elevation angle.-- either take the cos-1 of the number on a calculator, which is the angleOR-- look up the number in a table of cosines and see what angle it represents.
What is the angle of elevation for the ramp that is 20 feet away from the wall and 15 feet tall?
height = 15 ft base = 20 ft angle of elevation = arctan (15/20) = 36.87 degrees
Simple angle of elevation word problem?
A simple angle of elevation problem...You want to find out the height of a tree. You measure the distance from you to the base and find that it is 100 feet. You measure the angle of elevation of the top and find that it is 30 degrees. You are six feet tall. How tall is the tree?Answer: The tree is 64 feet tall. Its height is tangent 30 times 100 + 6.
How tall is the tree if it have a horizontal distance of 45m an a elevation of 26 degree?
If you are standing 45m from the base of the tree and an imaginary lines from the tip of the tree to the ground forms a 26° angle with the ground, then the tree is 21.95 m tall. (45m) * tan(26°) = 21.95 m
A surveyor stands on the roof of a building. The angle of elevation to the roof of the building next door is 25°. The angle of depression to the base of that building is 44°. The buildings are forty feet apart?
57 ft
A suspension bridge is supported from a height of 30 feet. The length of the wire used to suspend the bridge from the ground to the top is 65 feet. What is the angle of elevation from the base of the?
A suspension bridge is supported from a height of 30 feet. The length of the wire used to suspend the bridge, from the ground to the top, is 65 feet. What is the angle of elevation from the base of the bridge to the point of suspension?
Scott is standing 80 ft from the base of a tree He sees the top of the tree from an angle of elevation of 42 degrees His eye is 4.5 feet off the ground How tall is the tree?
Tangent of theta = Y/X, or opposite the angle/the adjacent of angle. So; Tangent of 42 degrees = height/80' 80' tan 42 = height = 72 feet ( you might want to subtract that 4.5 foot eye height )
The vertex angle of an isosceles triangle is twice as large as one of the base angles Find the measure of the vertex angle?
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
If a man 5 ft tall observes that the angle of depression of the base of the pole is 30 degrees and that the angle of elevation of the top of the pol is 60 degrees how high is the pole in feet?
25 feet
The angle of elevation from a boat to the top of a lighthouse is 35 degrees the lighthouse is 96 feet tall how far from the base of the lighthouse is the boat?
137 ft
