Answer:

30°

Step-by-step explanation:

knowing that the sum of the inner angles of a triangle is 180° , so we got the two angles (102° & 48°), so we add them then subtract it from 180°

180°-(102°+48°)=x

180°-150°=30°

x=30°

Answer:

x^2-5x + 6

Step-by-step explanation:

Here, we want to expand the given expressions

To do this, we multiply each term in the first bracket with each term in the second

We then proceed to collect like terms

We have this as;

x(x-3) - 2(x-3)

= x^2 - 3x -2x + 6

= x^2 -5x + 6

The correct answer is: [B]: " 9.6 cm " .
____________________________________________________________

Explanation:
____________________________________________________________

Let "FH" = "x" ; for which we wish to solve.

45 cm / 12 cm = 36 cm / "x" (in "cm") ;

To solve for "x" ;

Cross--multiply:

Note: Given:

" $\frac{a}{b} = \frac{c}{d}$ " ; " ad = bc " ; (b ≠ 0 ; d ≠ 0) ;

So: " 45x = 12 * 36 " ;

→ 45x = 432 ;

Divide each side of the equation by "45" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 45x / 45 = 432 / 45 ;

→ x = 9.6 cm ;
___________________________________________________________
→ which corresponds with:
___________________________________________________________

→ Answer choice: [B]: " 9.6 cm " .

The volume of an oblique pyramid with a square base is V units3 and the height is h units.

TiliK225 [7]

The volume of a quadrangular base pyramid is:
V = (1/3) * (Ab) * (h)
Where,
Ab: base area
h: height
Clearing the area of the base we have:
Ab = (3 * V) / (h)
Answer:
An expression that represents the area of the base of the pyramid is:
A) 3v / h units
