You begin by finding the measure of the angles knowing that all angles in a triangle equal 180.  Then you use tan 57=7/(line AC).  This value squared plus 7 squared will equal the length of the hypotenuse squared.

I need the answer and the work! <br> you have to find n.
zloy xaker [14]

Tell you what I'll do:  I'll show you the work, for two of them.
Then, knowing how to do it, you'll find the answers.
Deal ?

#1). n + (-13) = -12

Remove the parentheses
on the left side:                     n - 13 = -12

Add  13  to each side:           n        =    1

================================

#3).                        -15 + n  =  3

Add  15  to each side:     n  =  18


OK.  Look those over, understand how they're done, then TAKE IT !

256. Since each side is congruent, the length equals 8. 8 times 8 equals 64. Divide it by 2 to find the area of the triangle. 64 divided by 2 equals 32. Since there are 8 congruent triangles, 32 x 8 equals 256.

Determine if the data comes from a linear function or an exponential function. Then, enter
svet-max [94.6K]

1.  The data is not linear.  There's not a constant difference between the f(x) values.  (AKA there's not a fixed slope between the data points)

2. The data is exponential, because there's a consistent ratio in the f(x) values:

     189/567 = 1/3

     63/189 = 1/3

     21/63 = 1/3

     7/21 = 1/3

Each new y-value (aka f(x)-value) is 1/3 the previous value.

Also, f(0)=567.

If we put that together, we have f(x) = 567 (1/3)^x.
