Answer:

Is there a rigid transformation that maps triangle ABC to triangle ABD? If so, which transformation?

yes, because a translation to the right will map ΔABC to ΔABD

yes, because a rotation about point B will map ΔABC to ΔABD

yes, because a reflection across BA will map ΔABC to ΔABD

no, because no rigid transformation will map ΔABC to ΔABD

Chika's uncle makes perfect brownies. Chika noted how much sugar he uses based on how many batches

Alex

Answer:

7.5 batches

Step-by-step explanation:

if he uses 0.6kg of sugar per 2 batches, it's 0.3kg per batch.

2.25kg would let us make

2.25kg / 0.3kg = 2.25 / 0.3 = 7.5 batches

if 2 and 4 are factors of a number, is 8 also a factor of that number? I know it's false ( 12 is a multiple of 2 and 4 but not 8

Answer:

It would be false because 2 and 4 are factors which simply mean they can multiply togeher to get another number

In triangle $DEF,$ $\angle D = 30^\circ,$ $\angle F = 60^\circ,$ and $EF = 6.$ Find $DE + DF.$ [asy] unitsize(2 cm); pair D, E,

lesya692 [45]

Answer:

The answer is below

Step-by-step explanation:

In triangle DEF, ∠D = 30°, ∠F = 60° and EF = 6. Find DE + DF.

Solution:

A triangle is a polygon with three sides. There are different types of triangles such as isosceles triangle, scalene triangle equilateral triangle, right angled triangle.

In triangle DEF:

∠D + ∠E + ∠F = 180° (sum of angles in a triangle)

30 + ∠E + 60 = 180

∠E + 90 = 180

∠E = 180 - 90

∠E = 90°

This is a right angled triangle since one angle = 90° (∠E).

Using sine rule:

$\frac{|EF|}{sin(D)}=\frac{|DE|}{sin(F)} \\\\\frac{6}{sin(30)}=\frac{|DE|}{sin(60)} \\\\|DE|=10.39\\\\\frac{|EF|}{sin(D)}=\frac{|DF|}{sin(E)} \\\\\frac{6}{sin(30)}=\frac{|DF|}{sin(90)} \\\\|DF|=12\\\\$

Hence DE + DF = 12 + 10.39 = 22.39
