Solve for indicated side. Round to the nearest hundredth. b = 19 48
1 answer:
The trigonometric function gives the ratio of different sides of a right-angle triangle. The value of b is 50.76 units.
<h3>What are Trigonometric functions?</h3>
The trigonometric function gives the ratio of different sides of a right-angle triangle.
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.
The value of c can be found by using the cosine function of trigonometry, therefore, the value of b is,
Cos(19°) = 48/b
b = 48/Cos(19°)
b = 50.76579 ≈ 50.76 units
Hence, the value of b is 50.76 units.

Answer:
RS = 2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
RS² + RT² = TS² , that is
RS² + 6² = 8²
RS² + 36 = 64 ( subtract 36 from both sides )
RS² = 28 ( take the square root of both sides )
RS = =
= 2
≈ 5.3 ( to 1 dec. place )
