To find:To round side lengths to the nearest tenth and angles to the nearest degree.
Answer to Problem 1CYU
In
So side AC= b= 5.1
Angle
And Angle
Explanation of Solution
Given information:
The length of two sides of triangle ABC and one angle.
AB= 4
BC=3
Calculation:
To find the length of side AC, we use the cosine formula for any triangle:
Let AC=b
AB = c = 4
BC = a = 3
Or b =5.1
Also as we know that-
Since the sum of the angles of any triangle is
So
In triangle ABC
So side AC= b= 5.1
Angle
And Angle
