Answer:
exact form: x=20/9
decimal Form: x=2.222...
Step-by-step explanation:
Answer:
150
Step-by-step explanation:
the bases are 60 and the sides are 90
Answer:
17,13,11
Step-by-step explanation:
Writing this statement symbolically, we get:
n
--- - 5 = 8
2
Adding 5 to both sides, we get n/2 = 13. Then n = 26.
Let AB extended intersect DC extended at point E
<span>We now have right triangle BEC with E = 90 degrees </span>
<span>For triangle BEC: </span>
<span>Exterior angle at E = 90 </span>
<span>Exterior angle at C = 148 (given) </span>
<span>Exterior angle of all polygons add up to 360 degrees </span>
<span>Exterior angle at B = 360−148−90 = 122 </span>
<span>So in quadrilateral ABCD </span>
<span>B = 122 </span>
<span>D = 360−44−148−122 = 46</span>
