Answer:
Angle D is complementary to angle A
Step-by-step explanation:
Complementary angles sum to 90 degrees.
Since angle is B is 90 degrees, the sum of angles A and D are also 90 degrees to make a straight line with an angle measure of 180 degrees.
Answer:
I think it would be A
Step-by-step explanation:
If you are trying to figure out the distance between the top of the tree and the end of the shadow, use a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the legs of the right triangle.
5^2 + 4^2 = c^2
25 + 16 = c^2
41 = c^2
c = √41 = 6.4 meters
Aye the Answer is D ~hope that helps :)
