15/10 = 18-x/x is the ratio of the larger to the smaller triangle

Cross multiply:
15x = 10(18 - x)
15x = 180 - 10x
25x = 180
x = 7.2

Plug back in to check
15/10 = 1.5

18-7.2/7.2 = 10.8/7.2 = 1.5 :)

What is the equation of the line that goes through the points (-5,-1) and (5,5)?

Margaret [11]

Answer:

y = 3/5 x + 2.

Step-by-step explanation:

Use the point-slope equation of a straight line:

y - y1 = m (x - x1) where m = the slope amd (x1, y1) is a point on the line.

Here:

m = (5- (-1)) / (5 - (-5))

= 6/10

= 3/5.

Substituting for m and (5, 5):

y - 5 = 3/5(x - 5)

y - 5 = 3/5x - 3

y = 3/5 x + 2.

Please help, last unit of algebra 2, thankyou!!!!!!!!!!!!

Mumz [18]

Answer:

$\cot \theta = \frac{8}{15} \\\\\sec \theta = \frac{17}{8} \\\\\csc \theta = \frac{17}{15}$

Step-by-step explanation:

$\huge \tan \theta = \frac{15}{8} ...(given) \\ \\ \huge \because \: \cot \theta = \frac{1}{ \tan \theta} \\ \\ \huge \therefore \: \cot \theta = \frac{1}{ \frac{18}{8} } \\ \\ \huge \therefore \: \cot \theta = \frac{8}{15} \\ \\ also \\ \huge \sec \theta = \frac{17}{8} \\$
