Answer:
x = -14
Step-by-step explanation:
x + 6 = -8
-6 -6
x = -14
Answer:
The answer is No, according to the Triangle Theorem.
Step-by-step explanation:
When you have the sides of the triangle, you must be able to add up 2 sides and have a larger number than the other side.
4+5 = 9 which is greater than 1
5+1 = 6 which is greater than 4
4+1=5 which is equal but not greater than 5
Answer:yes
Step-by-step explanation:
Answer:
Multiply the moduli and add the arguments.Step-by-step explanation:First write out the two terms being multiplied: z1z2= [r1(cos(theta 1) + isin(theta 1))][r2(cos(theta 2)+ isin(theta 2))] z1z2= r1r2 (cos(theta 1) + isin(theta 1))(cos(theta 2)+ isin(theta 2)) z1z2= r1r2(cos(theta 1)cos(theta 2))+(icos(theta 1)sin(theta 2))+(icos(theta 2)sin(theta 1))+(i^2 sin(theta 1)sin(theta 2)) Next group and rewrite the like term with the sums and differences. Your answer is the multiplication of the moduli and the addition of the arguments: z1z2= r1r2[cos(theta 1 + theta 2) + i sin (theta 1 and theta 2)].
