List the angles in order from smallest to largest.
pychu [463]

Answer:

C) ∠C < ∠A < ∠B


Step-by-step explanation:

We determine the answer by visualizing a flat board with two adjustable pins and a loop of string 9 units long. Pull the string taut with a pencil and drag it to form an isosceles triangle.


To establish ∠C < ∠A, set the pins 3.2 units apart and label them A and C, with the pencil point B. Initially AB = BC = 2.9 units, and ∠C = ∠A. Move the pencil leftward so AB decreases to 2.8 units and BC increases to 3.0 units. Clearly angle A increases and angle C decreases.


To establish ∠A < ∠B, set the pins 2.8 units apart and label them A and B, with the pencil point C. Initially AB = BC = 3.1, and ∠A = ∠B. Move the pencil rightward so BC decreases to 3.0 units and AC increases to 3.2 units. Clearly angle B increases and angle A decreases.

Answer:

DC=2.4

Step-by-step explanation:

let DC=x

AB=4-x

\frac{3}{4.5} =\frac{4-x}{x} =\frac{4}{x} -\frac{x}{x} =\frac{4}{x} -1\\\frac{4}{x} =\frac{30}{45} +1=\frac{30+45}{45} =\frac{75}{45} =\frac{5}{3} \\5x=4*3=12\\x=12/5=2.4

7/8 x+ 3/4 x+ 7/16 x− 1/16 = 5/8
EleoNora [17]

Answer:

Therefore x  =\frac{1}{3}

Step-by-step explanation:

\frac{7}{8} x+\frac{3}{4} x+\frac{7}{16} x-\frac{1}{16} =\frac{5}{8}

\Leftrightarrow \frac{7}{8} x+\frac{3}{4} x+\frac{7}{16} x =\frac{5}{8}+\frac{1}{16}

\Leftrightarrow \frac{14x+12x+7x}{16}  =\frac{10+1}{16}         [ L.C.M of 8,4,16 =16 and  L.C.M of 8,16 =16]

\Leftrightarrow \frac{33x}{16}  =\frac{11}{16}

\Leftrightarrow x  =\frac{11\times 16}{16\times 33}

\Leftrightarrow x  =\frac{1}{3}

Therefore x  =\frac{1}{3}
