Step-by-step explanation:
15)
In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is .
The angle of the other triangle plus the angle
of the right-angle triangle is equal to 90º, therefore they are complementary angles.
So,
To find ?, we have
16)
The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is
Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have
we know that
If square GYTD is translated units left and
units up to produce square G'Y'T'D'
that means
the rule of transformation is
<u>Find the coordinates of the image</u>
therefore
<u>the answer is the option</u>
G'(−6, 5), Y'(−2, 5), T'(−2, 1) , and D′(−6, 1)
