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:

<h2>7 + 8 = 98</h2>

Step-by-step explanation:

2 + <em>3</em> = <u>8</u>

<u>8</u> : 2 = 4; 4 - 1 = <em>3     (subtract 1)</em>

3 + <em>7</em> = <u>27</u>

<u>27</u> : 3 = 9, 9 - 2 = <em>7     (subtract 2)</em>

4 + <em>5</em> = <u>32</u>

<u>32</u> : 4 = 8; 8 - 3 = <em>5     (subtract 3)</em>

5 + <em>8</em> =<u>60</u>

<u>60</u> : 5 = 12, 12 - 4 = <em>8     (subtract 4)</em>

6 + <em>7</em> = <u>72</u>

<u>72</u> : 6 = 12, 12 - 5 = <em>7     (subtract 5)</em>

7 + <em>8</em><em> </em>= <u>x</u>

<u>x</u> : 7 = y, y - 6 = <em>8     (subtract 6)</em>

Solve:

y - 6 = 8         <em>add 6 to both sides</em>

y - 6 + 6 = 8 + 6

y = 14

<u>x</u> : 7 = y ⇒ <u>x</u> : 7 = 14 ⇒ <u>x</u> = (14)(7) ⇒ <u>x</u> = 98

A right triangle has side lengths 7, 24, and 25 as shown below.
Alla [95]

9514 1404 393

Answer:

  • tan(A) = 7/24
  • sin(A) = 7/25
  • cos(A) = 24/25

Step-by-step explanation:

The mnemonic SOH CAH TOA can help you remember the trig ratios:

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

With respect to angle A, the sides are Adjacent = 24; Opposite = 7, Hypotenuse = 25. Then the desired trig ratios are ...

  tan(A) = 7/24

  sin(A) = 7/25

  cos(A) = 24/25
