Step-by-step explanation:
since the triangle CDE is an isoceles triangle (the 2 legs DC and DE are equally), the 2 angles at its baseline CE are equal.
combined with the fact that the sum of all angles in a triangle is always 180 degrees we can therefore say :
180 = 32 + 2× base angle
148 = 2× base angle
base angle = 74 degrees.
the angle DEC is one of these base angles and therefore 74 degrees.
and because of the symmetry of angles of crossing lines, this is equal to the angle AEB.
the triangle AEB is also an isoceles triangle. the angle A is one of its base angles at the baseline AB.
so, the same principle as before :
180 = 74 + 2× base angle
106 = 2× base angle
base angle = 53 degrees.
so, angle A is 53 degrees.

0.4 out of the 0.8/ for the 3.5 it should be 1.5
The ordered pair (1, 40) represents the unit rate of the relationship.
The ordered pair (3, 120) means that Tien can type 120 words in 3 minutes.
Answer:
64.94
Explanation
You arrange the numbers in such a way, to be in line with their decimal points like this:
70.7
-5.76
Then you subtract. Notice that on top of the 6 is nothing which is equal to 0
