Answer:
7.6 inches
Step-by-step explanation:
We solve the above question using the Law of Cosines.
The formula is given as:
h² = i² + j² - 2ij Cos H
h = √i² + j² - 2ij Cos H
From the above question:
i = 6.6 inches
j = 6.4 inches
Length h = ?
Angle H=62º.
Hence:
h= √6.6² + 6.4² - 2 × 6.6 × 64 × Cos 62
h = √43.56 + 40.96 - 84.48 × Cos 62
h = 7.64292 inches
Approximately to the nearest tenth, Length h = 7.6 inches

Answer:
a = -50/51
Step-by-step explanation:
1 + 2a + 3 + 4a + 5 + 6a + ...... + 97 + 98a + 99 + 100a = 0
1 + 3 + 5 + ... + 99 + 2a + 4a + ... + 98a + 100a = 0 Eq. 1
99 + 97 + 95 + ... + 1 + 98a + 96a + ... + 4a + 2a = 0 Eq. 2
Add Eq. 1 and Eq. 2
100 + 100 + ... + 100 + 102a + 102a + ... 102a = 0
50(100)/2 + 50(102a)/2 = 0
2500 + 2550a = 0
2550a = -2500
a = -2500/2550
a = -250/255
a = -50/51
