Answer:
m∠T = 45°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
∠S + ∠T + ∠U = 180°
2x + 10 + 3x - 9 + 6x - 19 = 180
11x - 18 = 180
11x = 180 + 18
= 198
x = 198 ÷ 11
x = 18
m∠T = 3x - 9
= 3(18) - 9
= 54 - 9
m∠T = 45°
<h3><u>The correct answer is A and B.</u></h3>
Both A and B represent functions, as the same x value is not used twice.
However, with option C, the x value -2 is used twice, and thus it is not a function.
The solution of the value is mathematically given as
√6 =2.449
This is further explained below.
<h3>What is square Root?</h3>
Generally, In mathematics, the term "square root" refers to a component of a number that, when multiplied by itself, results in the same value as the original number.
As an example, both 3 and –3 are square roots of the number 9.
A number y is said to have a square that is equal to a given number x if and only if it satisfies the following condition: y2 = x.
Another way to express this is to say that the number y has the same value as its own square. For example, the square roots of 16 are 4 and -4, since 42 divided by 2 is 16.
In conclusion,
√6 is not -4
because
√6 =2.449
