Alisiya [41]3 years ago
6 0

Answer:

see explanation

Step-by-step explanation:

Using the identity

cos²Θ = 1 - sin²Θ

Consider the left side

sin²Θ - cos²Θ

= sin²Θ - (1 - sin²Θ ) ← distribute parenthesis by - 1

= sin²Θ - 1 + sin²Θ

= 2sin²Θ - 1

= right side , thus verified

There are four highlights in the paragraph that show equations or phrases
aivan3 [116]

A reflection across the line y=0 (AKA the x-axis)

and then across the line x=0 (AKA the y-axis)

is the same as a rotation of 180º

clockwise about the origin because the lines intersect at the origin and at a 90º angle.

While all of that is true, you could also be more general, because reflecting over any two lines that intersect at the origin will result in a rotation about the origin and have an angle of rotation equal to twice that of the acute angle formed between the intersecting lines.

If a rectangle measures 20 meters by 48 meters, what is the length, of the diagonal of the rectangle? Can you help me with this
Vikki [24]
the \ width \ of \ the \ rectangle : \ w=20 \ m \\ \\ the \ length \ of \ the \ rectangle : \ l=48 \m \\ \\ Diagonal : \ \sqrt{w^2 + l^2}\\ \\D =\sqrt{20^2 + 48^2} \\ \\D=\sqrt{400+2304}=\sqrt{2704}= 52 \ m

18. Given the following four lines, pick the true statement.
Sav [38]

Answer:

Lines 2 and 4 are perpendicular

Step-by-step explanation:

Line 2: 4y=3x-4

y=3/4x - 1

Line 4: 4x+3y=-6

3y=-6-4x

y=-2 - 4/3x

The two lines are perpendicular since -4/3= - (inverse of 3/4)
