The value of cos 45 in a right angle triangle is 1/√2.

<h3 /><h3>What is the trigonometry ratio?</h3>

The trigonometry ratios are ratios that can be used to determine the side and angles of a triangle depending on the known parameter. The basic trigonometry ratios are denoted by the acronym: SOH CAH TOA

i.e.

  • Sin θ = opp/hyp
  • Cos θ = adj/hyp
  • Tan θ = opp/adj

From the given diagram, we are to find the Cos 45°

i.e.

θ = 45°

Let's recall the angle 45 45 90 theorem that states that right angles have the following values for the sides:

  • hypotenuse = √2
  • opposite = 1
  • adjacent = 1

Since

Cos θ = adj/hyp

Cos 45 = 1/√2

Answer:

  D)  When 10 movies are streamed in a month; the total price that month is $28.

Step-by-step explanation:

Using the function definition, put 10 where you find m, then evaluate:

  p(10) = 2(10) +8 = 20 +8

  p(10) = 28

The function definition tells you this (28) is the price of streaming 10 movies in a month.

The measure of ∠FHJ is 60°. The measure of ∠FGH is 28°.<br><br><br><br> What is the measure of ∠HFG?
Hatshy [7]
<span>Given
∠FHJ = 60°
</span><span>∠FGH =  28°

</span>∠FHG = 180 - ∠FHJ
∠FHG = 180 - 60
∠FHG = 120


∠HFG = 180 - (28 + 120)
∠HFG = 180 - 148
∠HFG = 32
