The calculated length of side qs is 2.4
How to determine the length of side qs
From the question, we have the following parameters that can be used in our computation:
The triangle
The length of side qs can be calculated using the following law of cosines
qs² = rq² + rs² - 2 * rq * rs * cos(R)
Substitute the known values into the equation
qs² = 1.2² + 1.4² - 2 * 1.2 * 1.4 * cos(134 deg)
This gives
qs² = 5.73
Take the square root of both sides
qs = 2.4
Hence, the length of side qs is 2.4
