Answer:
Step-by-step explanation:
Given
AB = 48, AC = 64, and BC = 80
Required
Determine the ratio of cosB
The first step is to determine, which type of triangle it is.
Checking for Right Angled Triangle
For a triangle to be a right angled triangle, the square of the largest side must be equal to the sum of squares of other sides
This implies that:
<em>Hence, the triangle is a right angled triangle [See attachment]</em>
From trigonometry;
The adjacent of B = 48 while the hypotenuse is 80;
Hence;
Hence, the ratio of cos B is
Cos C is equal to
The adjacent side is 36 and the hypotenuse is 45, so using the formula:
The answer is cos C = 0.8
Answer:
(7,-1)
Step-by-step explanation:
common rule for reflections across the origin; im guessing you meant a reflection across the line y=x since it goes through the origin too.
for this make sure to add this transformation:
(x,y) --> (-x,-y)
