Answer:

C. 27

Step-by-step explanation:

well we can use the pythagorean theorem for this and disregard the 11. so we have the hypotenuse and one side so therefore a^2+b^2=c^2 and if we plug in the numbers it would look like this

16.5^2+x^2=29^2

272.25+x^2=841

x^2=568.75

and from multiple choice we can infer that the answer is obviously bigger than 16.5 because in the picture x is a longer side but it is smaller than 29 and the only answer in between those two numbers given would be C. 27

Write an equation for a line that has slope of 4 and y- intercept of 7

grigory [225]

Answer:

y = 4x + 7

Step-by-step explanation:

the equation for a line is y = mx+b

the y intercept is (0,7)

so in the equation x= 0 and y= 7 and the slope is m, thus m= 4

7= (4)(0)+b

now solve for b

7 = 0 +b

7= b

so the equation of the line would be without the x and y points

y = 4x + 7

How many solutions does a triangle with side lengths a = 4, A = 112º and b =<br>9 have?

Ainat [17]

Answer:

This case has NO solutions.

Step-by-step explanation:

Notice that you are in a case of an obtuse triangle (one of its angles is larger than 90 degrees), the side opposite to the obtuse triangle is shorter than the side adjacent to the angle, so no actual triangle can be formed.

This can be found by simply trying to apply the Law of Sines to solve for the value of angle "B" opposite to side "b":

$\frac{sin(A)}{a} =\frac{sin(B)}{b}\\sin(B)=\frac{b\,sin(A)}{a}\\sin(B)=\frac{9\,sin(112^o)}{4}\\\\sin(B)=2.086$

As shown above, we get an impossible mathematical condition (also call an absurd), since the sine of an angle cannot give a value larger than 1 (one).

Therefore, there is no angle we can find to build a triangle with the given data.
