Answer:

10

Step-by-step explanation:

<h3>Calculating BC</h3><h3>BC = √2^2 + 11^2 </h3><h3>BC = √ 4+121</h3><h3>BC = √ 125 = 11.18</h3>

to find measure of angle C use sinerule

<h3>sinC/C = sinA/A</h3><h3>sinC/2= Sin90/11.18</h3><h3>SinC = 2×1/11.18</h3>

<h3>sinC = 2/11.18</h3><h3>sinC = (0.1788)</h3><h3>C = sin^-1(0.1788)</h3>

<h3>C = 10.305</h3><h3>C = 10 (approximately)</h3>

Which of the following functions is graphed below?
denis-greek [22]

The option that is the functions is graphed below is known as option A = Y= (x+4) -2.

<h3>What is the function about?</h3>

The function graphed above is Y=|x+4|-2 because  when you solve for the graphs,  the number in the x-axis is always changed or turned to  the other side and there one can see that it would be -4 would be +4, and +4 and also -4.

Note that

Y = (x+4) -2.

x = (0 + 4) - 2

x = 4-2

x =2

Therefore, plug x into the equation.

Y = (x+4) -2.

= ( 2 + 4) - 2

= (6) -2

= 4

Therefore, The option that is the functions is graphed below is known as option A = Y= (x+4) -2.

What 2 numbers that are the same multiply to be 36 and add up to be 15?
marysya [2.9K]
The only way to have two numbers that are the same and add up to be 15
is if they're both 7.5 , but those don't multiply to be 36.  So I guess there's
no answer that satisfies all the conditions of this question.
