Need help on the question 6

Mathematics
1 answer:
netineya [11]2 years ago
5 0

Answer:

d. 42 degrees

Step-by-step explanation:

y and 92 are supplemetary angles, which means they both add up to 180 since they are on the straight line.

Hence,

y+92 = 180

y = 180-92

y=88

And now we also know that all the angles of a traingle add up to 180,

so, we can simply find the x by:

88+x+50 =180

138 + x =180

x = 180-138

x = 42

Hope this helps!

Find all solutions of the equation. 5 sin x − 82√ = 3 sin x − 72√
Andrei [34K]

Answer:

  • x = arcsin(√20.5 -3√2) +2kπ . . . k any integer
  • x = π - arcsin(√20.5 -3√2) +2kπ . . . k any integer

Step-by-step explanation:

Add √(82) -3sin(x) to both sides to get ...

  2sin(x) = √82 -√72

Now, divide by 2 and find the arcsine:

  sin(x) = (√82 -√72)/2

  x = arcsin((√82 -√72)/2)

Of course, the supplement of this angle is also a solution, along with all the aliases of these angles.

___

In degrees, the solutions are approximately 16.562° and 163.438° and integer multiples of 360° added to these.
