Answer:
34.7 degrees
Step-by-step explanation:
This is a right triangle trig problem. The angle in question, the angle of elevation, is the base angle that is NOT the right angle. The height of the tree is the side opposite the angle of elevation, and the distance away from the tree is the measure of the base of the right triangle. So the question, then, is "What is the angle that has a ratio equal to the side opposite the angle over the side adjacent to the angle?" This is the definition of the tangent of an angle. The equation will be set up as follows:
Your calculator needs to be in degree mode when you do this operation. Press 2nd on your calculator then tan and you'll get tan^-1 on your display. This means you are looking for a missing angle. Enter the fraction as 45/65 inside the parenthesis and hit enter and you'll get an angle of 34.69515353. Round to the nearest tenth for 34.7
You will always use the 2nd and sin/cos/tan buttons to find missing angles.
-1/4 i think, Y1-Y2/X1 -X2= the slope . -9-3= -12 and -6 - (-9)= -6 +9= 3. So simplify 3/-12 makes -1/4.
Answer:
B'C'D'
Step-by-step explanation:
The figure was just translated, without any deformation, these are similar figures... so their corresponding angles are the same.
Since it was just moved down by 4 units, none of the angles were changed, and none of the side lengths were changed.
Since vertex C' corresponds to vertex C, the angle B'C'D' corresponds to original angle BCD.
C.) y=log1X is not a logarithmic function because the base is equal to 1. XD
Just took the test!!
Sorry I didn't see this earlier
