Logarithms are only able to make an equation linear if it is an exponential function. For example,
can be made linear by taking the natural logarithm of each side, causing it to become
. After some simplifying, you are left with
. You are then able to plot ln(y) vs. x to get a linear fit.
Let's calculate the value of angle A and B
sin(A) =-4/5 → sin⁻¹(- 4/5) = A → A = - 53.13
cos(B) = -5/13 → cos⁻¹ (- 5/13) = B → B = 112.62
tan (A+B) = sin(A+B)/cos(A+B) with A+B = -53.13 + 112.62 = 59.49
tan (A+B) = sin(59.49)/cos(59.49) = 0.86154/0.507688 = 1.6969.
(Answer H = 56/33 = 1.6969)
Angles in a triangle ALWAYS equal 180 degrees, so 180-59-63= final angle (58 degrees) Then just use (Tan,Cos,Sin) with the angles to find the lengths, i can’t answer it as i don’t know what the triangle looks like
Change in number of seats = 144 - 111 = 33
percentage increase = 33/111 x 100 = 29.8% (nearest tenths)
7 plus 3 first than plus 2 my strategy is to look at the easier thing to add than add the second one
