Find the value of the unknown angle X.

kupik [55]

Answer:

x = $130^{o}$

Step-by-step explanation:

The given figure is a trapezium which is a quadrilateral with four sides.

But,

Sum of angles in a quadrilateral = (n - 2) x 180

where n is the number of sides.

For a quadrilateral, n = 4. So that,

Sum of angles in a quadrilateral = (4 - 2) x 180

= 2 x 180

= $360^{o}$

The sum of angles in a quadrilateral is $360^{o}$ .

Thus,

$158^{o}$ + $51^{o}$ + $x^{o}$ + $21^{o}$ = $360^{o}$

$x^{o}$ + $230^{o}$ = $360^{o}$

$x^{o}$ = $360^{o}$ - $230^{o}$

= $130^{o}$

The value of x is $130^{o}$ .

ABC and EBF are a pair of vertical angles; mABC = 3x + 8 and mEBF = 2x + 48. What are mABC and mEBF?

natita [175]

Vertical angles are angles opposite to each other when two lines cross.
what's interesting is that vertical angles are equal.

Based on this:
angle ABC = angle EBF
3x + 8 = 2x + 48
x = 40

measure angle ABC=measure angle EBF =
3(40)+8 = 128 degrees

The 50th term of an arithmetic sequence is 86 and the common difference is 2. Find the first three terms of the sequence.

Nesterboy [21]

$a_n=a_{n-1}+d=a_{n-2}+2d=\cdots=a_1+(n-1)d$

which means

$a_{50}=86=a_1+49\times2\implies a_1=-12$

which in turn means the next two terms are $a_2=-10$ and $a_3=-8$ .
