Answer:
x = 125°, y = 55°, z = 70°
Step-by-step explanation:
x and 55 are adjacent angles and are supplementary, sum to 180°, that is
x + 55° = 180° ( subtract 55° from both sides )
x = 125°
∠ ABD and ∠ BDC are alternate angles and congruent , so
y = 55°
Since BD and BC are congruent, then Δ BCD is isosceles, so
∠ BDC = ∠ BCD = 55° and
z = 180° - (55 + 55)° ← angle sum of triangle
= 180° - 110°
= 70°
well, my idea is plot a line on XOY plane. let the number line as x-axis, make y-axis, we just need a line that cross (1/6,0) for example y = x/6 - 1/6, next we need two simple pair number (x,y) on the line as base to draw the line we can choose (1,0) and (7,1). x-intersect that line is desired 1/6 position on the number line
They are both quadrilatersand they are both parallelograms
Answer: Eleven Fourths xEight Ninths.
Step-by-step explanation: To get the mixed number Eleven Fourths, you have to multiply 4x2 (4 as the denominator and 2 as the whole number) to get 8, and add 3 (numerator) to get 11, and then put 4 over it as the original denominator to get 11/4. Then, just plug back in the numbers: 11/4 x 8/9 (Eleven-Fourths times Eight-Ninths)
