Add 87. 92, 75, & 83 together and divide by the number of tests she has taken. so in this case it would be four. 84.25!!
Answer:
B
Step-by-step explanation:
Angle ABD is congruent to angle CBD--->Definition of perpendicular lines
Segment DB is congruent to Segment Db--->Reflextive property of congruence
Angle ADB is congruent to angle CDB--->angle bisector theorem
2 angles and 1 side is congruent, therefore <em><u>the triangles are congruent by the ASA Congruence Theorem</u></em>
1/4(12 + x)
3 + 1/4x
The solution is 3 + 1/4x
Answer:
√13 ≈ 3.6056
Step-by-step explanation:
The Law of Cosines can be used to figure this. If the third side is "c", then it tells you ...
c² = a² + b² - 2ab·cos(C)
c² = 3² + 4² -2(3)(4)(cos(60°)) = 9 + 16 - 24(1/2) = 13
c = √13 ≈ 3.6056
The length of the third side is √13, about 3.6056.
Answer:
The cost of posting one letter = £1.68
Step-by-step explanation:
Total amount Amina has = £20
Amina's change = £14.96
Total cost spent on posting the letters = £20 - £14.96 = £5.04
And we're told that she posts 3 letters in total, with the cost of posting each letter the same.
Cost of posting 3 letters = £5.04
Cost of posting only 1 letter = (£5.04/3) = £1.68
Hence, the cost of posting a letter = £1.68
Hope this Helps!!!
