Answer:
x=-4
Step-by-step explanation:
These two angles have to equal 180 because they are opposite of each other. Therefore, the equation will be 129+x+x+59=180. You add all common terms. 2x+188=180. You want to isolate x so you have to subtract both sides by 188. Therefore, the equation will be 2x=-8. Divide both sides by 2 to isolate x. x=-8/2. This is equal to x=-4.

Answer:
The reflexive property of congruence allow us to say that RST = RST .
Option (C) is correct .
Step-by-step explanation:
Definition of Reflexive Property of congurence
The meaning of Congruence is figure has the same size and shape. If you were comparing something to itself, then it definitely have the same size and shape this is called Reflexive Property of congurence .
By using Reflexive property of congurence .
RST = RST
Therefore reflexive property of congruence allow us to say that RST = RST .
Option (C) is correct .
Answer:
Step-by-step explanation:
complex roots always occur in pairs.
roots are 1,2-2i,2+2i
P(x)=a(x-a)(x-b)(x-c)
P(x)=1(x-1)[x-(2-2i)][x-(2+2i)]
=1(x-1)[(x-2)+2i][(x-2)-2i]
=(x-1)[(x-2)²-(2i)²]
=(x-1)[(x-2)²-4i²]
=(x-1)[x²-4x+4-4(-1)]
=(x-1)[x²-4x+4+4]
=(x-1)[x²-4x+8]
=x³-4x²+8x-x²+4x-8
=x³-5x²+12x-8
Answer:
201
Step-by-step explanation:
If a number is 5 or over, then you round a number up. However, if it is less than 5, then you keep the same number.
