Two of the angles of a triangle measure 40° and 100°. Classify the triangle
Ksju [112]

Hey there!

All of the given angles of a triangle will always add up to 180 degrees. Therefore, our angle measures are 100, 40, and 40. There are 3 types of triangle classifications based on angles.

Acute: all three angles are less than 90 degrees.

Right: one angle is 90 degrees.

Obtuse: has an angle that is greater than 90 degrees.

As you can see, we have one angle that is greater than 90, which is 100.

Therefore, this is an obtuse triangle.

I hope this helps!

A tree is leaning at a 5° angle from vertical, making an 85° angle with the ground. When the sun is at a 65° angle of elevation,
Vinvika [58]
D = 25 ft is the length of a shadow. L -  the length of a tree.
Two angles are 85° and 65° and the third is 180° - ( 65° + 85° ) =
= 180° - 150° = 30°.
We will use the Sine Law:
25 / sin 30° = L / sin 65°
25 / 0.5 = L / 0.9063
25 * 0.9063 = 0.5 L
22.6577 = 0.5 L
L = 22.6577 : 0.5
L = 45.3 ft.
Answer: the approximate length of the tree is 45.3 ft.
