I think it is 8. im not sure
Answer:
∠C = 106.7°, ∠D = 73.3°, CD = 104.4
Step-by-step explanation:
As shown in the diagram attached, let a point E be made on line BD.
Hence, BE = 130 m
BE + ED = BD
ED = BD - BE
ED = 160 m - 130 m = 30 m
Also, CE = 100 m
Using Pythagoras theorem in triangle CDE:
CD² = CE² + ED²
CD² = 100² + 30²
CD² = 10000 + 900 = 10900
CD = √10900
CD = 104.4
Using sine rule in triangle CDE:
In trapezoid ABCD, the sum of angles in a quadralateral is 360°, hence:
∠A + ∠B + ∠C + ∠D = 360
90 + 90 + ∠C + 73.3 = 360
∠C + 253.3 = 360
∠C = 360 - 253.3
∠C = 106.7
Answer:
I dont know and i also dont know why im doing this.
Step-by-step explanation:
15% of 25 = 3.75
0.15 x 25 = 3.75
All you have to do is divide the score by how many questions there are.
Score = 36
Total = 50
36 ÷ 50 = 0.72
0.72 = 72%
Answer = 72%
Hope this helped :)
