Answer: -204
Step-by-step explanation: 12 X -17 +Y is the same thing but you can say it this way and its easier to understand but it equals -204/(negative 204) Hope this helps you! :3
Answer:
c
Step-by-step explanation:
you have vertical angles are equal then ED=AB
and CD=CB
SAS
we want<u> </u><u>CE=CA</u> <u>(C)</u>
Just like regular numbers, angles can be added to obtain a sum, perhaps for the purpose of determining the measure of an unknown angle. Sometimes we can determine a missing angle because we know that the sum must be a certain value. Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees.
The angles of this triangle are 50, 60, and 70 degrees.
X = length of half the base
If you draw out a triangle, the horizontal leg will be x, the vertical leg will be 147 and the angle of inclination (or angle of elevation) is 52 degrees
You'll use tangent to find x
tan(angle) = opposite/adjacent
tan(52) = 147/x
x*tan(52) = 147
x = 147/tan(52)
x = 114.84 ... this is approximate
Half the base is 114.84, so the full base is 2*114.84 = 229.68 which rounds to 230
The final answer is D.
One fourth 1/4. just reduce five tenths to one half
