Question

Find the value of 4 sin 30° + 3 tan 45​

Answer 1

Step-by-step explanation:

sin30=½

tan45=1

so

4(½) + 3(1)

2+3

=5

have a nice day

Answer 2

Given:

4 sin 30° + 3 tan 45​°

To find:

The value of 4 sin 30° + 3 tan 45​°

Solution:

The value of 4 sin 30° + 3 tan 45​° is 5.

We can determine the value by following the given steps-

We know that the value can be obtained using the rules of trigonometry.

Using trigonometry,

Sin 30°=1/2

Tan 45°=1

Now, we will substitute the values of sin 30° and tan 45°.

On putting the values, we get

=4 sin 30° + 3 tan 45​°

=4×1/2 + 3×1

=4/2+3

=2+3

=5

So, 4 sin 30° + 3 tan 45​°=5.

Therefore, the value of 4 sin 30° + 3 tan 45​° is 5.
