3•-13/8 is -4.875 or or -4 7/8
The answer is 15.01
First you need to find the other angle of the triangle so you do 90+25 which gives you 115 and subtract that by 180 because all angles of a triangle add up to 180. That gives you 65 then you will use TAN(65) and get 2.144506920509559 which you will then multiple by 7 to get 15.01154844356691 which you then round to get 15.01!
function : y = (-x) - 6
<u>Find x-intercept</u> :
<u>Find y-intercept</u> :
mark these two points on both the axis and draw a straight linear graph.
passes coordinates : (0, -6), (-6, 0)
