To find the numerical value of the given trigonometric expressions, we need to evaluate each trigonometric function individually and then add them together.
1) sin 30°: The sine function of 30° is equal to 1/2.
2) cos 60°: The cosine function of 60° is equal to 1/2.
3) tan 45°: The tangent function of 45° is equal to 1.
So, sin 30° + cos 60° tan 45° = 1/2 + 1/2 * 1 = 1/2 + 1/2 = 1.
Thus, the numerical value of the given expression is 1.
1) sin 30°: The sine function of 30° is equal to 1/2.
2) cos 60°: The cosine function of 60° is equal to 1/2.
3) tan 45°: The tangent function of 45° is equal to 1.
So, sin 30° + cos 60° tan 45° = 1/2 + 1/2 * 1 = 1/2 + 1/2 = 1.
Thus, the numerical value of the given expression is 1.
