Answer:
<u>The correct answer is that 4√- 2 is the simplest radical form of this mathematical expression and 8i (i = imaginary unit) is the solution if we want to find out the square root of a negative signed number.</u>
Step-by-step explanation:
1. Let's write in a mathematical expression the information given:
Sum square root of -2 and the square root of - 18
√- 2 + √ - 18
√- 2 + √ 9 . - 2 ( 9 * -2 = - 18)
√- 2 + 3 √ - 2 (√ 9 = 3)
4 √- 2
This is the simplest radical form of this mathematical expression. If we want a concrete number, we should remember that if we refer to the imaginary numbers we can find the solution for √-2 = 2i, or for any other negative number, where i is the imaginary unit. This unit can be used for the development of the square root of negative signed numbers.
Then,
4 √- 2 = 4 (2i) = 8i
<u>The correct answer is that 4√- 2 is the simplest radical form of this mathematical expression and 8i (i = imaginary unit) is the solution if we want to find out the square root of a negative signed number.</u>
Answer:
B.) 113°
Step-by-step explanation:
In the isosceles trapezoid, angles T and S are congruent. Find the value of x:
Subtract 4x from both sides:
Add 38 to both sides:
Divide both sides by 3:
x is equal to 15. Now substitute the value of x into the one of the expressions:
or
The angles T and S are 67°.
The angles of a trapezoid will always add up to a total of 360°, so add the angles T and S:
Subtract their total from 360:
The total of the angles Q and R is 226°. Since this is an isosceles trapezoid, those two angles are also congruent. Divide the value by 2:
Angle R is 113°.
Done.
