Opposite angles are equal

$\\ \rm\longmapsto m+357=4m+6$

$\\ \rm\longmapsto 357-6=4m-m$

$\\ \rm\longmapsto 3m=351$

$\\ \rm\longmapsto m=\dfrac{351}{3}$

$\\ \rm\longmapsto m=117$

For a finite sequence of nonzero numbers, the number of variations in sign is defined as the number of pairs of consecutive term

elena55 [62]

Answer:

The no. of variations in sign is 3

Step-by-step explanation:

Variation in sign occurs when every single time a negative product is produced by a pair of consecutive terms.

Therefore, the determination of the number of changes in sign in the given sequence is must.

Therefore, we take the product of the pair of consecutive terms as:

$1\times (-3)$ = - 3, variation in sign

$(-3)\times 2$ = - 6, variation in sign

$2\times 5$ = 10, no sign variation

$5\times (- 4)$ = - 20, variation in sign

$- 4\times (-6)$ = 24, no sign variation

The right answer is Option A: $x=\frac{rs-t}{2}$

Step-by-step explanation:

Given expression is;

$s=\frac{2x+t}{r}$

We will solve this expression for x, therefore,

Multiplying both sides by r

$r*s=\frac{2x+t}{r}*r\\rs=2x+t$

Subtracting t from both sides

$rs-t=2x+t-t\\rs-t=2x\\2x=rs-t$

Dividing both sides by 2

$\frac{2x}{2}=\frac{rs-t}{2}\\x=\frac{rs-t}{2}$

The right answer is Option A: $x=\frac{rs-t}{2}$

Find the value of x

GalinKa [24]

Answer:

29 degrees

Step-by-step explanation:

9: 2x - 2 + x + 5 = 90

3x + 3 = 90

3x = 90 - 3
