Answer:
21300
Step-by-step explanation:
3 keeps 50 the same, and if the number is below 4 then the number stays the same, if it's 5 and up the number goes up by one digit.
Answer:
Perimeter is 17.07
Step-by-step explanation:
We know that DF = EF = 5 cm, since D and E are the midpoints of AC and AB, both of which are 10 cm in length.
We need to use the Pythagorean theorem to get the length of DE.
So the perimeter of DEF is 5 + 5 + 7.07 = 17.07
The second choice is correct. Given that angle 2 and angle 6 are congruent, the largest in each of the corresponding triangles are vertical angles meaning that two known angles are known in each triangle (and they are equal) which means that the last "unknown" (angles 3 and 7) are congruent. The lines DC and AB correspond with these defined, congruent triangles meaning they are parallel.
I believe its -1 because x2-x1/y2-y1 good luck
5x + 50 +x
= 5x*2( square ) + 50
