Answer:

56.6m

Step-by-step explanation:

Using SOH = opp/hyp

Where θ = 45°

Hpy = 80m

Opp = ?

Sin θ = opp/hpy

Sin 45 = opp/ 80

Sin 45 × 80 = opp

0.7071 × 80 = opp

Opp = 56.568

~ 56.6m

Hence the height of the top of the tree is 56.6m

Write each as the sum of two terms in the form t_n,r. t_5,3 , t_11,2 , t_15,13
Anarel [89]

The sum of two terms are:

  • t₅, ₃ = 8
  • t₁₁, ₂ = 13
  • t₁₅,₁₃ = 28.

<h3>What is the sum about?</h3>

The sum of two numbers is one that tells you to find the sum of two or more numbers, and as such, you have to add the numbers altogether.

t₅, ₃ =  5 + 3

= 8

t₁₁, ₂ = 11 + 2

= 13

t₁₅,₁₃ =  15 + 13

= 28.

Hence the correct sum of two terms are:

  • t₅, ₃ = 8
  • t₁₁, ₂ = 13
  • t₁₅,₁₃ = 28.
