Answer:
-55
Step-by-step explanation:
It would be -55 because the exponent is 4. So, that would leave -55 to be the right answer.
Answer:
Option B
Step-by-step explanation:
step 1
Find the measure of angle A
Remember that the sum of the interior angles of a triangle must be equal to 180 degrees
∠A+∠B+∠C=180°
substitute the given values
∠A+23.4°+90°=180°
∠A+23.4°+90°=180°-113.4°=66.6°
step 2
Find the length of side BC (a)
Applying the law of sines
c/sin(C)=a/sin(A)
3.3/sin(90)=a/sin(66.6)
a=3.3*sin(66.6)/sin(90)
a=3.0 mm
step 3
Find the length side AC (b)
Applying the law of sines
c/sin(C)=b/sin(B)
3.3/sin(90)=b/sin(23.4)
b=3.3*sin(23.4)/sin(90)
b=1.3 mm
Answer:
i
Step-by-step explanation:
i = 
⇒ i² = ( )² = - 1 , then
= i² × i² × i
= - 1 × - 1 ×i
= 1 × i
= i
