CAN SOMEONE HELP ME FIND THE DISTANCE..​
kirill115 [55]

The angle of elevation from point C to point A is 32^{\circ}

<em><u>Solution:</u></em>

Given that we have to find the angle of elevation from point C to Point A

Given in figure that, angle A = 58^{\circ}

Given is a right angled triangle ABC where angle B = 90^{\circ}

We have to find angle C

The angle sum property of a triangle states that the angles of a triangle always add up to 180°

Therefore, in given triangle ABC

angle A + angle B + angle C = 180

58^{\circ} + 90^{\circ} + C = 180^{\circ}

148^{\circ} + C = 180^{\circ}\\\\C = 180^{\circ} - 148^{\circ}\\\\C = 32^{\circ}

Therefore angle C = 32^{\circ}
