Given an angle $\theta$ , any angle of the form $\theta+360^\circ n$ where $n$ is an integer is coterminal with $\theta$ .

This means $-110^\circ$ is coterminal with $-110^\circ+360^\circ=250^\circ$ .

5 through 6 equation: a²+b²=c²
5) 5²+.8²=c²
25+.64=c²
√25.64=√c²
√25.64=C or 5.063=C
6) 2²+8²=c²
4+64=c²
√68=√c²
√68=C or 8.246=C

I hope this was of help

A 12-foot ladder leans against the wall; the base of the ladder is 2 feet away from the wall.To the nearest tenth of a foot, how

ludmilkaskok [199]

<h3>The ladder will reach a height of 11.8 feet up the wall</h3>

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

The ladder, wall and base of the ladder from wall forms a right angled triangle

Length of ladder forms the hypotenuse

Length of ladder = 12 foot

base of the ladder from wall = 2 feet

<em><u>To find: height of wall</u></em>

By pythagoras theorem.

$c^2 = a^2+b^2$

Where,

"c" is the Length of ladder

"a" is the base of the ladder from wall

"b" is the height of wall

Substituting the values,

$12^2 = 2^2+b^2\\\\144 = 4 + b^2\\\\b^2 = 140\\\\b = \pm 11.832 \\\\Ignore\ negative\ value\\\\b \approx 11.8$

Thus, the ladder will reach a height of 11.8 feet on wall
