Answer:
I think it is the 5th one if im wrong i am sorry
Step-by-step explanation:
There are 2 triangles here. You have to drop an altitude and determine the length of it. You can use the fact that sin45 = h/5 (h is the height) and get that the height is 3.5. The rule then is if h is smaller than b which is in turn smaller than c, you have 2 triangles. This is the case of the ambiguous triangle, that SSA that you cannot use to prove congruency. The rules are very particular for whether or not 0, 1, or 2 triangles exist. Learn them.
Step-by-step explanation:
The horizontal stretch or compression for a function f(x) is given by g = f(bx) where b is a constant. If b> 0 then the graph of a function is compressed.
As it is given in the question that the function is transformed by a compression factor of 3.
Given function
The value of k will be 3 if the function is transformed by a compression factor of 3
I took a19=-58 divide it by 19 both side i get a = -58÷19 (note; you can never have a neg. # on the top bring the neg. down to the bottom and divide) now its 58÷-19= -3.05 or -3 (1÷19) so a = -3(1/19) do the same to the other now. answer is a=-7 (17/21)
Answer:
x=14
Step-by-step explanation:
Since the triangles are similar, you first line up the sides. Then, because the 16 and the 24 line up together, you divide them to find out how much bigger the first triangle is, which is 3/2 or 1.5. After that, you can see that the 21 and the x are on the same side, so you would divide 21 by 1.5 or 3/2 to get x. 21÷1.5=14.
x=14
