1. <A= sin a/c

= sin 26/31

=sin 0.8387=57degree

<A= 57degree

2.<B= cos a/c

= cos 26/31

= cos 0.8387=33degree

<B = 33degree

3.<C=90 degree cause it already gave us the sign of perpendicular sign

4. B=(c^2 - a^2)square root

=(31^2-26^2)square root

=(961-676)square root

=(285)square root

 $\sqrt{285}$

Find m angle T, rounded to the nearest degree

Butoxors [25]

Answer: First option.

Step-by-step explanation:

You can use the inverse tangent function to find the value of the angle T:

$\alpha=arctan(\frac{opposite}{adjacent})$

You can identify in the figure that:

$\alpha=T\\opposite=RG=8\\adjacent=TR=15$

Then, knowing these values, you can substitute them into $\alpha=arctan(\frac{opposite}{adjacent})$ .

Therefore, you get that the value of the angle T rounded to the nearest degree is:

$T=arctan(\frac{8}{15})\\\\T=28\°$

This matches with the first option.
