Find KI if GI = 3.2<br> Can anyone help??
Juliette [100K]

Answer:

I don't know if I'm right I've never done this before but it seems like GI is exactly half of that line so the other half must be 3.2.

Correct me if I'm wrong thank you, and wait for more responses if needed please.

If a line passes thru the points (4,5) and (2,9) the slope of this line is
Allisa [31]

Answer:

m=-2

Explanation:

If a line passes through the points (4,5) and (2,9): to calculate the slope, use the formula below:

\text{Slope,m}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}

Substituting the points, we have:

\begin{gathered} m=\frac{9-5}{2-4} \\ =\frac{4}{-2} \\ =-2 \end{gathered}

The slope of this line is​ -2.

30 POINTS HELP ANSWER ASAP AND EXPLAIN STEP BY STEP HOW TO SOLVE The two non-parallel sides of an isosceles trapezoid are each 7
weeeeeb [17]
See diagram
I wrote that the degrees are 70 each because it is isocolese and 140/2=70


a.
to solve for the diagonal, I'm going to use trig to find the height and the base then use pythagorean theorem to find the diagonal

so
see I've drawn an auxiliry line to make a right triangle on the leftmost side
so
we want to find the height and base
sin(70°)=h/7
so 7sin(70°)=h≈6.57785

cos(70°)=base/7
so 7cos(70°)=base≈2.39414

now
the entire long base is 22, so that big triangle with the diagonal as the hyptonuse is 22-2.39414=19.6059
use pythagorean theorem, like 6.57785²+19.6059²=diagonal²
we get that the diagonal is about 20.68ft




b.
we got that the base was 7cos(70°)
2 of those bases so 22-14cos(70°)=17.2117ft or rounded 17.21ft




a. 20.68ft
b. 17.21ft
