Answer:
43.5√3 sq. units
Step-by-step explanation:
Base 1 of trapezoid is 10.
Base 2 of trapezoid is 16 + 3 = 19
The height = 3√3 (To get the height you had to multiply the number 3 from the bottom base of the trapezoid by the square root of three)
Now plug these numbers into the trapezoid formula: A = 1/2(3√3)(10 + 19)
Simplify to get: 43.5√3 sq. units
Hope this helps you understand! P.S. I helped someone else out on this problem, so I just copied and pasted my answer from the previous brainly question onto here. :) So, it's still my own work.
A) 1:3. Add 16, 4, 20, and 8= 48. Then simplify 16:48 = 2:6 = 1:3 :)
Answer:
8. Not similar
9. Similar
Step-by-step explanation:
8. You could try to us the AA theorem which means that two angles in the triangle are equal, which would mean that the triangles are similar. But 46+58=104 and 180-104=76 so there are not two similar angled between the triangles.
9. You can use the same theorem for this problem (AA). So 106+31=137 and then 180-137=43 which is one of the angles in the second triangle. Since at least two of the angles are equal, you can use AA theorem yo prove they are similar.
Hope this helps!
