SOLUTION

From the given value

Since

\sin u=\frac{7}{25}

Then using trigonometrical ratios it follows

\cos u=\frac{24}{25}

Using hal -ngle it folows

\begin{gathered} sin(\frac{u}{2})=\sqrt{\frac{1-\frac{24}{25}}{2}} \\ s\imaginaryI n(\frac{u}{2})=\sqrt{\frac{1}{50}} \end{gathered}

Also

\begin{gathered} cos(\frac{u}{2})=\pm\sqrt{\frac{1+\frac{24}{25}}{2}} \\ cos(\frac{u}{2})=\sqrt{\frac{49}{50}} \\ cos(\frac{u}{2})=7\sqrt{\frac{1}{50}} \end{gathered}

Finally?

\begin{gathered} \tan(\frac{u}{2})=\pm\sqrt{\frac{1-\frac{24}{25}}{1+\frac{24}{25}}} \\ \tan(\frac{u}{2})=\sqrt{\frac{1}{49}} \\ \tan(\frac{u}{2})=\frac{1}{7} \end{gathered}

The value of 3 in 46.132 is how many times the value of the 3 in 8.553<br><br>A 10<br>B 1 <br>C 1/10
kifflom [539]

Answer:

The value of 3 in 46.132 is 10 times the value of 3 in 8.553.

Step-by-step explanation:

The value of 3 in 46.132 is in hundredth's place.

The value of 3 in 8.553 is in thousandths place.

We can write as :

For 46.132, its value is \dfrac{3}{100} and for 8.553 its value is \dfrac{3}{1000}.

Taking,

\dfrac{\dfrac{3}{100}}{\dfrac{3}{1000}}=10

So, the value of 3 in 46.132 is 10 times the value of 3 in 8.553. Hence, the correct answer is A.

Please help me- AND PLEASE EXPLAIN
GuDViN [60]

Answer:

A=35, B=55, and C=25

Step-by-step explanation:

Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.

if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B

Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.
