20.25 hope this helps
Step-by-step explanation:
Answer: 20 ft
Step-by-step explanation:
The mirror is set away from the flagpole on the same scale set away from her.
The distance she stand's away from the mirror is 1/4 of the length of the distance between the mirror and the flag pole because she's 1/4 of the flagpole's size.
This means her size x4 is the size for the flag pole. This checks out because 12x4=48
So to find the height we must do 5x4
5x4=20
X= 5
To find the side a we will use the Pythagorean Theorem:
<span><span>a2</span>+<span>b2</span>=<span>c2</span></span>
After substituting <span>b=12</span> and <span>c=13</span> we have:
<span><span>a2</span>+<span>122</span>=<span>132</span></span><span><span>a2</span>=<span>132</span>−<span>122</span></span><span><span>a2</span>=169−144</span><span><span>a2</span>=25</span><span><span>a=5</span></span>
Answer:
Adjacent - DBC and ABC, EBA and ABC
Vertical - ABC and DBE, CBD and EBA
Step-by-step explanation:
A vertical pair of angles are opposite to each other and intersect by two lines. They make an x shape.
Adjacent angles are angles that have a common vertex and side but do not overlap. They make a v shape with another line in the middle.
