Answer:
Step-by-step explanation:
tanA = sinA/cosA = (4/7)/(3/7) = 4/3
Answer:
rise over run is 1/4
Step-by-step explanation:
Here, we want to calculate the ratio of the rise to the run
Mathematically, this is simply referring to the slope
To get the slope, we need to select any two points and then apply the slope formula
The two points selected are;
(8,-6) and (-4,-9)
The slope formula is;
m = (y2-y1)/(x2-x1) = (-9 -(-6))/(-4-8) = -3/-12 = 1/4
SA= Lateral Area + Area (of base)
Lateral area = perimeter of base x height
An isosceles triangle has two congruent base segments. The hypotenuse of an isosceles right triangle is (length of base segment) x (the square root of 2). I did the math for you (shown above) to get 5 as a base.
So 5 + 5 + square root of 50 is your perimeter
Multiply the perimeter times your height (8) and you get the lateral area.
Add your lateral area to the base area (triangle = 1/2 bh)
LA = 136.568...
Area of Triangle base = 12.5
Surface area = 149.068... square cm
