Answer:

63°

Step-by-step explanation:

To get the value of x we will use the Pythagoras theorem

hyp² = opp²+adj²

Given

hyp is the length of the ladder = 22ft

Adjacent is the distance from the base of the ladder to the wall = 10ft

Angle of elevation = x

Using the SOH CAH TOA identity

Cos theta = adjacent/hypotenuse

Cos x = 10/22

Cos x = 5/11

x = arccos(5/11)

x = arccos(0.4545)

x = 62.96°

Hence the best estimate of x is 63°

Answer:

115°

Step-by-step explanation:

The sum of angle measures of a pentagon is 540°, so your unknown angle can be found from ...

... 103° + 100° +110° +112° +unknown = 540°

... unknown = 540° -425° = 115° . . . . . . . . subtract 425° from both sides

<em>Angles of a polygon</em>

The external angles lf a convex polygon always sum to 360°. The sum of internal and external angles is, of course, 180°. So, an n-sided polygon has internal angle measures that sum to ...

... n×180° - 360° = 180°×(n -2)

Thus, a pentagon has internal angles that sum to ...

... 180°×(5 - 2) = 540°
