In a triangle if two angles measure 65 degrees and 25 degrees, what is the measure of the third angle and what is the type of triangle?

The measurement of the third angle is 90 degrees

Step-by-step explanation:

There are 180 degrees in a triangle.

180 - 65 = 115 - 25 = 90

It is a right angled triangle

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
