Sin tita + sin ^2 tita = 0

Mathematics
1 answer:
AnnyKZ [126]3 years ago
3 0

Answer:

tita = 0 , 180, 270, 360.   ( tita =  0   ≤ x ≤ 360).

Step-by-step explanation:

sin tita + sin ^2 tita = 0

sin tita( sin tita + 1) = 0

sin tita = 0, - 1.

For angles between 0 and 360 inclusive  sin = 0 gives 0, 180 and 360 degrees.  The angle whose sine is -1 is 270 degrees.

tita = 0 , 180, 270, 360.

Determine which equation has the same solutions as the given equation. x2 − 10x − 11 = 0
cupoosta [38]

The equation x² − 10x − 11 = 0 that is equivalent to (x – 5)² = 36. Then the correct option is A.

<h3>What is an equivalent expression?</h3>

The equivalent is the expressions that are in different forms but are equal to the same value.

The equation is given below.

x² − 10x − 11 = 0

Then the equation can be written as

x² − 10x + 25 – 25 − 11 = 0

                        (x – 5)² = 36

Then the correct option is A.

The complete question is attached below.

More about the equivalent link is given below.

Answer:

8 is the length of JB

Step-by-step explanation:

<u>Key skills needed: Equations, Congruence</u>

1) We need to find out an equation to make based on the lengths that are given. ΔJMB is congruent to ΔKMB because of Side-Angle-Side:

  • JB is congruent to BK
  • Angle MBK would be a right angle, since it is supplementary to the right angle JBM. Since both are right angles they are congruent.
  • Both triangles have the side BM. Using the reflexive property, BM is congruent to itself, so there you go --> Side-Angle-Side

2) Now since both triangles are congruent, we can make the equation that the length of JM is congruent to the length of MK, using the fact that: If triangles are congruent, then corresponding parts are congruent.

3) This means that 16x -24 = 4x

Subtract 16x from both sides : -24 = -12x

Divide by -12 on both sides and get x = 2

4) Substitute x into the length of JB (16x-24)

16(2)-24 = 32-24 = 8

5) Therefore, the length of JB is 8
