Work out the value of [tex]$h$[/tex] in the following equation:

[tex]h \sin 38^{\circ} = 1.5[/tex]

Give your answer to 2 decimal places.


Sagot :

Sure, let's solve the equation step-by-step:

Given the equation:
[tex]\[ h \sin 38^\circ=1.5 \][/tex]

To find [tex]\( h \)[/tex], we need to isolate [tex]\( h \)[/tex] on one side of the equation. We can do this by dividing both sides of the equation by [tex]\( \sin 38^\circ \)[/tex]:

[tex]\[ h = \frac{1.5}{\sin 38^\circ} \][/tex]

First, let's determine the value of [tex]\( \sin 38^\circ \)[/tex]. The sine of 38 degrees is:

[tex]\[ \sin 38^\circ \approx 0.6156614753256583 \][/tex]

Now, substitute this value into the equation:

[tex]\[ h = \frac{1.5}{0.6156614753256583} \][/tex]

Perform the division:

[tex]\[ h \approx 2.436403868224116 \][/tex]

To give the answer to two decimal places, we round 2.436403868224116 to two decimal places:

[tex]\[ h \approx 2.44 \][/tex]

Therefore, the value of [tex]\( h \)[/tex] is approximately [tex]\( 2.44 \)[/tex].
