From the given situation above, we form a right triangle with legs equal to the height of the tree and the length of the shadow it casted. The hypotenuse is the length from the tip of the tree to the tip of the shadow.
The angle at which the ray of the sun hit the ground is that which has a tangent equal to 100 / 150 or 2/3. This angle is equal to 33.69. Thus, the answer is letter B. 34°.
Answer:
147 ft²
Step-by-step explanation:
14 x 14 = 196
7 x 7 = 49
196 - 49 = 147
Vertex<em> </em>is at
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
Step-by-step explanation:
The graph of the equation is hereby attached in the answer area.
Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here(), is shown with the dotted line in the graph attached.
<em>y-intercept </em>is defined as the value of y where the graph crosses the y-axis. In other words, when . Putting
And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of in the given equation . Here, co-efficient of
So, vertex<em> </em>is at
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
8n + 4 >= 28
8n >= 24
n >= 3
Values of n which makes this inequality true could be 3,4 and 5.
Answer:
tridecagon/triskaidecagon
Explanation:
sum of interior angles= <span>180<span>(n−2)</span></span> degrees, n being the number is sides in the polygon.
sum of interior angles= 1980
<span>180<span>(n−2)</span>=1980</span>
divide by 180:
<span>n−2=<span>1980180</span>=11</span>
add 2:
<span>n=11+2=13</span>
If a polygon has 13 sides, it is called a tridecagon or a triskaidecagon.
