In the figure below, sin 62 degrees - 17/c. based on the figure, which of the following equations is also true ?
a. cos 62 degrees = 17/c
b. tan 62 degrees = c/17
c. cos 28 degrees = 17/c
d. sin 28 degrees = c/17

Therefore Based on the Figure only the third option i.e C. ic True

Step-by-step explanation:

Given:

Let label the figure first such that

In Δ ABC , ∠C = 90° , ∠ B = 62°,

AB = Hypotenuse = c

AC = 17

To Find:

True Statements

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

Substituting the values we get

In Right Angle Triangle ABC , Cosine Identity we have

Substituting the values we get

Here in this figure

Substituting we get

Therefore Based on the Figure only the third option i.e C. is True

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
