Answer:

  • 7) x = 5
  • 8) x = 20

Step-by-step explanation:

Complementary angles form a right angle and supplementary angles form a straight angle.

<h3>#7</h3>

<u>Complementary:</u>

  • 65 + 5x = 90
  • 5x = 25
  • x = 5
<h3>#8</h3>

<u>Supplementary:</u>

  • 2x + 6x + 20 = 180
  • 8x = 160
  • x = 20

Step-by-step explanation:

1)

Since we know that sum of two complementary angles are 90⁰

=> 65 + 5x = 90

=> 5x = 90 - 65

=> 5x = 35

=> x = 35/5

=> x = 7⁰

2)

Since we know that sum of two supplementary angle are 180

=> 2x + 6x + 20 = 180

=> 8x = 180 - 20

=> 8x = 160

=> x = 160/8

=> x = 20

If a(n)=24 which recursive formula could represent the sequence below? <br> ...,24,88,664,8408,...
sesenic [268]
24= 3*2^3  
88= 11*2^3
664= 83*2^3 -> 83=11+72 = 11 + 2^3*3^2
664=2^3 (11+2^3*3^2) = 88 +(2^3*2^3*3^2) = 88 +(24^2)

8408= 1051 * 2^3 -> 1051= 83+968 -> 968 = 2^3 * 11^2
8408= 2^3 (83+2^3*11^2) = 664 +(2^3*2^3*11^2) = 664 +(88^2)

So: 
a(n) = a(n-1) + a(n-2)^2

Lets check: 88+24^2= 664
664+88^2= 8408
