In triangle rst, rs = 6 cm, st = 7 cm, and rt = 8 cm. what is the approximate measure of the largest angle in the triangle?

The approximate measure of largest angle is 76°

Step-by-step explanation:

Given in triangle RST, RS = 6 cm, ST = 7 cm, and RT = 8 cm. we have to find the measure of the largest angle in the triangle.

By theorem If one side of a triangle is longer than the another side, then the angle opposite to the longer side of triangle will be larger than the angle opposite to the shorter side.

As longest side is RT.

∴ the angle opposite to the side RT is largest i.e ∠S is largest.

By cosine law,

⇒

The approximate measure of largest angle is 76°

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
