Answer:
(3,-7)
Step-by-step explanation:
Midpoint Formula
(3,-9) = ((3+x)/2 , (-11+x)/2)
Solve for x coordinate
Solve for y coordinate
Therefore point s is (3, -7)
Answer: 3n-6
Step-by-step explanation: You have to use the distributive property. 3 times n is 3n and 3 times -2 is -6.
Answer: A) Copy the angle
When you are constructing triangles when given a Side, Angle, and Side (SAS), you should first copy one of the side.
Then, you should copy the angle that is between the sides. (That is the answer to your question)
Finally, you will copy the last side. Then, you will have congruent triangles.
Answer:
55.4
Step-by-step explanation:
Think of it as a right angled triangle, the length of the ladder (17ft) is the hypotenuse, the length of the ground (14ft) is the rise, we then use sin to get the angle as the angle of elevation is the angle between the ladder and the ground hence sin^-1 (14/17) and you get your angle.
