I need the value of x

Mathematics
1 answer:
Lyrx [107]3 years ago
8 0

Answer:

8

Step-by-step explanation:

∠1 = (6x + 2)° (vertically opposite angles are equal)

15x + 10° +∠1 = 180° (co-interior angles are equal)

15x + 10° + 6x + 2° = 180°

15x + 6x + 10° + 2° = 180°

21x + 12° = 180°

21x = 180° - 12°

21x = 168°

x = 168/21

x = 8

hope u understood!

∠1 and ∠2 are supplementary angles. If m∠1 = 77°, then m∠2 =
posledela

Answer:

B. 103°

Step-by-step explanation:

Supplementary angles add up to 180°, so we can find the measure of angle 2 by subtracting 77 from 180

180 - 77

= 103

So, m∠2 is 103°

Find all solutions to the equation (sinx-cosx)^2=1
svetoff [14.1K]

Answer:

x=\dfrac{\pi k}{2},\ k\in Z.

Step-by-step explanation:

Simplify the equation (\sin x-\cos x)^2=1:

\sin^2 x-2\sin x\cos x+\cos ^2x=1,\\ \\ (\sin^2x+\cos^2x)-2\sin x\cos x=1.\\

Since

\sin^2 x+\cos^2 x=1

and

2\sin x\cos x=\sin 2x,

we have

1-\sin 2x=1,\\ \\\sin 2x=0,\\ \\2x=\pi k,\ k\in Z,\\ \\x=\dfrac{\pi k}{2},\ k\in Z.

Which statement accurately describes how adding a number, n, to the function f(x)=sin(x) affects its graph?
Hitman42 [59]

The <em>correct answer</em> is:


A) There is a vertical shift of n units.


Explanation:


When a parent function is transformed, each type of transformation results ina different change in the graph.


The parent function in this question is f(x) = sin(x).


Adding n units to the end of this function would result in f(x) = sin(x) + n.


When a function is transformed by adding a constant to the end of a function results in a vertical shift by that number of units. In this case, it would be a vertical shift n units.
