When completing the proof to show that corresponding angles AKG and ELK are congruent, Michael completed the proof wrongly.
<h3>What are corresponding angles?</h3>
It should be noted that corresponding angles are the angles that occupy the same relative position at each intersection.
From the information, when completing the proof to show that corresponding angles AKG and ELK are congruent, Michael completed the proof wrongly because the second statement shows that they're not Al vertically angles.

Area of circle: A=pi×r². This area coresponds to 360degrees, or 2×pi radians.
2×pi ....... pi×r²
t radians....x
where t=2.75rads
Area of t: x=pi×r²×t/2/pi=r²×t/2
Area of t: 3²×2.75/2=9×2.75/2=12.375
Answer: the area of 2.75 radians is 12.375
Answer:
D. 296 square inches
Step-by-step explanation:
The surface area of a prism is the total area of all its faces.
A triangular prism has three rectangular faces and two triangular faces.
As all 3 sides of the triangle face of this prism are equal, each of the 3 rectangular faces are also equal in area.
<u>Formulae</u>
- Area of a triangle = 1/2 x base x height
- Area of a rectangle = width x length
From inspection of the diagram:
⇒ Area of a triangle = 1/2 x 8 x 7 = 28 in²
⇒ Area of a rectangle = 8 x 10 = 80 in²
<u>Total surface area</u>
Total surface area = 3 rectangle areas + 2 triangle areas
= (3 x 80) + (2 x 28)
= 296 in²
Repeatedly add 20 and then subtract 7
Answer:
9
Step-by-step explanation:
the answer is 9 because 7 goes into 63 evenly 9 times
