Answer: real numbers have to be whole (maybe negative) but no fractions or decimal answers. 23 is also an integer. so the answer is A
Step-by-step explanation:
-2 + 4i + 1 - 7i + 8 - 5i
7 - 8i
Never true because if the product is 10 and the two numbers are 5 & 2 if you add them it won't give you 10 it will give you 7 so therefore the answer is never true
Answer:
1)B:63°
2)A:59°
Step-by-step explanation:
1.ABC is a right triangle at C then angle ACB=90°(right angle)
Angle CAB=27°(see the given)
measure of the angles in any triangle is 180°
then angle CBA=
measure of all the angles - (measure ACB+measure CAB)
=180°-(90°+27°)
=63°
2. Same explanation of angle B:
in the right triangle DEF: angle DEF=90°
angle D=31°(given)
Then measure of angle A=180°-(angle E + angle D)
=180-(90+31)=59°
