(05.03 mc) the figure below shows a square abcd and an equilateral triangle dpc: abcd is a square. p is a point inside the square. straight lines join points a and p, b and p, d and p, and c and p. triangle d ted makes the chart shown below to prove that triangle apd is congruent to triangle bpc: statements justifications in triangles apd and bpc; dp = pc sides of equilateral triangle dpc are equal in triangles apd and bpc; ad = bc sides of square abcd are equal angle adc = angle bcd = 90° so angle adp = angle bcp = 30° triangles apd and bpc are congruent sas postulate which of the following completes ted's proof? (1 point) in square abcd; angle adc = angle bcd in square abcd; angle adp = angle bcp in triangles apd and bpc; angle adp = angle bcp

Step-by-step explanation:

Here, ABCD is a square, and P is a point inside the square.

Where, Δ DPC is a equilateral triangle.

Therefore, DP=PC

Thus In triangles  APD and BPC,

DP= CP

( because both are of 30°)

AD=CB ( sides of square)

Therefore by SAS postulate,

Δ APD≅Δ BPC

it would be 6xy and -16xy.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
