Answer:
the shorter piece is 11 inches long
Step-by-step explanation:
x+2x=33in
3x=33in
33/3 = 11 =x
Answer:
650%
Step-by-step explanation:
There are 2 angle measurements not identified.
Angle ACB and angle ABC.
To find angle ACB you need to know that a straight line is 180 degrees, so if the angle to the right is 131, the angle to the left (Angle ACB) must be 49 degrees.
To find angle ABC, you need to know that the sum of all 3 angles in a triangle equal 180 degrees, so 180 - (49 + 44) = 87 degrees. Angle ABC is 87 degrees.
Answer:
x = 1/2 ± √2 / 2
Step-by-step explanation:
4x²-4x-1=0
Roots: x = (-b ± √b² - 4ac) / 2a a=4 b=-4 c=-1
x = (- -4 ± √(-4)² - 4*4*(-1)) / 2*4
x = (4 ± √32) / 8 = (4 ± 4√2) / 8 = 1/2 ± √2 / 2
The numerator and denominator of your answer is realtead to the model because the denominator is all of the parts and the numerator is the parts crossed out or shaded.
