Write the cosine ratio of angle b and show work please

Dennis_Churaev [7]

The formula for cosine is adj/hyp. For angle B, 10 is the adjacent and 24 is the opposite. The hypotenuse ( in this case, 26) is the longest side. the ratio for angle b would be 10/26.

5y + (86 - y) = 86 + 4y

Viefleur [7K]

Answer:

All real values, (-∞, ∞)

Step-by-step explanation:

Step 1: Distribute

5y + (86 - y) = 86 + 4y

5y + 86 - y = 86 + 4y

Step 2: Combine like terms

5y + 86 - y = 86 + 4y

4y + 86 = 86 + 4y

Step 3: Subtract 4y from both sides

4y + 86 - 4y = 86 + 4y - 4y

86 = 86

Step 4: Subtract 86 from both sides

0 = 0

Answer: All real values, (-∞, ∞)
