What is the next number? 2+3=8 3+7=27 4+5=32 5+8=60 6+7=72 7+8=?

ale4655 [162]

Answer:

Step-by-step explanation:

2 + 3 = 8

8 : 2 = 4; 4 - 1 = 3 (subtract 1)

3 + 7 = 27

27 : 3 = 9, 9 - 2 = 7 (subtract 2)

4 + 5 = 32

32 : 4 = 8; 8 - 3 = 5 (subtract 3)

5 + 8 =60

60 : 5 = 12, 12 - 4 = 8 (subtract 4)

6 + 7 = 72

72 : 6 = 12, 12 - 5 = 7 (subtract 5)

7 + 8 = x

x : 7 = y, y - 6 = 8 (subtract 6)

Solve:

y - 6 = 8 add 6 to both sides

y - 6 + 6 = 8 + 6

y = 14

x : 7 = y ⇒ x : 7 = 14 ⇒ x = (14)(7) ⇒ x = 98

Answer:

$\large\boxed{B.\ \cos(37^o)=\dfrac{x}{14}}$

Step-by-step explanation:

$sine=\dfrac{opposite}{hypotenuse}\\\\cosine=\dfrac{adjacent}{hypotenuse}\\\\tangent=\dfrac{opposite}{adjacent}\\\\\text{We have}\ adjacent=x\ \text{and}\ hypotenuse=14.\\\text{Therefore it's a cosine.}$
