X is either 25 or 45
Usimov [2.4K]3 years ago

For this case, we have that by definition:

Let "x" be an angle of any vertex of a right triangle.

tangent (x) = \frac {Cathet \ opposite} {Cathet \ adjacent}

So, if we want to find the angle x of the triangle shown we have:

tangent (x) = \frac {13} {6}\\x = arc \ tangent (\frac {13} {6})\\x = 65.23

Rounding:

x = 65\ degrees

Answer:

65 degrees

Option d

The length of the hypotenuse of a 30-60-90 triangle is 9. What is the perimeter?
denis23 [38]
The perimeter of any figure, is all its sides summed up

now, notice the picture below, using the 30-60-90 rule, that's "x"

now, get the other sides, since you know what "x" is, and sum them up, that's the perimeter

This is 70 points I will report anyone who answers wrong just for points! I will be asking TWO questions Please answer correctly
Ratling [72]




QUESTION 1: In these type of question, the easiest way to get the answer is try to plug in the x and y values from the options given in the equation given, So in the first question all the choice except C are more then 14 if you plug in x and y's, for eg, if you plug in x = 3 and y = 2 , you get (3+3)2 = 14 6 x 2 = 14 12 is not equal to 14, so this eliminates this choice but if you chose C you get, (11+3)1 = 14 14 = 14 so this makes C the solution for first question and for the second question do the same thing, and the answer will be D. Hope this helps




QUESTION 2: 5xy + 9 = 44

5xy = 35

xy = 7

solution pairs are:

C. (1, 7) and (7, 1)

not mentioned: (-1.-7) and (-7, -1)






Hope this helps
