Answer:
61°
this triangle is split in half and forms 2 triangles. These triangles must be congruent since they are each excatly half of this rectangle
Therefore, <2 is going to be equal to the m< the corresponding angle in the other triangle. <2 = 61°
<2 is also equal to 61° by the interior angles theorem
Step-by-step explanation:
Answer:
Can you please add the options.
Step-by-step explanation:
Divide both sides by 2
a-c=2a
minus a fromboth sides
-c=a
<span>The first step in finding the surface area of a cone is to measure the radius of the circle part of the cone. The next step is to find the area of the circle, or base. The area of a circle is 3.14 times the radius squared (<span>πr2</span><span>). Now, you will need to find the area of the cone itself. In order to do this, you must measure the side (slant height) of the cone. Make sure you use the same form of measurement as the radius.
You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (</span>πrl<span>).
So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:</span>
