(Help) Find the measure of the missing angle

Mathematics
1 answer:
melisa1 [442]3 years ago
8 0

Solution:

Let the missing angle be x.

<u>It should be noted:</u>

  • The two diagonals form four isosceles triangles. (ΔBOC, ΔCOD, ΔDOA, and ΔAOB)
  • ∠DOA = ∠BOC = 44 (Vertically opposite angles)
  • Interior angles of a triangle sum up to 180°

<u>This means that...</u>

  • 44 + x + x = 180

<u>Combine like terms.</u>

  • 44 + 2x = 180

<u>Subtract 44 both sides.</u>

  • 2x = 180 - 44

<u>Simplify the RHS</u>

  • 2x = 136

<u>Divide 2 both sides.</u>

  • 2x/2 = 136/2
  • => x = 136/2 = 68°

Answer:

see explanation

Step-by-step explanation:

(8)

the common ratio r,  of a geometric sequence is

r = \frac{a_{2} }{a_{1} } = \frac{a_{3} }{a_{2} } = ......

r = \frac{\frac{1}{32} }{\frac{1}{256} } = \frac{\frac{1}{4} }{\frac{1}{32} } = 8

(9)

The simplest way to evaluate the sum is to substitute k = 3, 4, 5, 6 into each term and sum them

(- 9 + 20) + (- 12 + 20) + (- 15 + 20) + (- 18 + 20)

= 11 + 8 + 5 + 2 = 26
