The answer is <span>SAS (side, angle, side) SAS stands for "side, angle, side" and means that we have two </span>triangles<span> where we </span>know<span> two sides and the included angle are equal. If two sides and the included angle of one </span>triangle<span> are equal to the corresponding sides and angle of another </span>triangle, thetriangles<span> are </span>congruent<span>.</span>
Answer:
Is B. 21 miles.
Step-by-step explanation:
I have the same question before.
Answer:
18 sides
Step-by-step explanation:
with regular polygons it is best to remember that:
(1) all the EXTERIOR angles add up to 3600
(2) 1 exterior angle+1 interior angle =1800
Work with the exterior angles. In this case:
1 int. <=180−160=200
No. of sides =36020=18
Well 3/4 is equal to 6/8
so you would do 60x6=360
