We know that
in the triangle ACB
∠ACB+90+34=180-----> ∠ACB=180-(90+34)----> ∠ACB=56°
∠ACD and ∠ACB-----> are supplementary angles
so
∠ACD+∠ACB=180-----> ∠ACD=180-56----> 124°------> x=124°
the answer Part 1) is x=124°
Part 2)
∠ACB+∠BCF+80=180-----> ∠BCF=180-(∠ACB+80)---> 180-(56+80)
∠BCF=180-136----> 44°-----> y=44°
the answer Part 2) is y=44°

Step-by-step explanation:
X. The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

Answer:
33.33 square yards
Step-by-step explanation:
Recall that 1 yd = 3ft.
(20 ft)(15 ft) = 300 ft^2
Converting this to square yards, we multiply the above result by
(1 yd)^2
------------
(3 ft)^2
obtaining
(300 ft^2) (1 yd)^2
-------------- * ------------- = 33.33 square yards
1 9 ft^ 2
Let the measure of the angle be x and from that the measure of its complement is 90 - x. The equation that best represent the given condition above is,
3x = (90 - x) - 14
The value of x from the equation above is 19. Thus, the answer is letter A.
