Answer:
look up answer key realy would help
Step-by-step explanation:
On a right triangle, to find one missing side you can use this equation
a^2 + b^2 = c^2
a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).
You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.
To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10
Now that you know the length of the dotted line is 10 units, you can now solve for x
(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361
I think the answer is the Last one
Answer:
thanks thanks thanks thanks for your points
Step-by-step explanation:
In this right triangle we have the opposite and adj which is tangent
tan 37=9/x
since we have the x in the bottom so we switch it with tan37
which is
x=9/tan 37
x=11.94340339
x=11.94
