Answer:

B. 60deg

Step-by-step explanation:

Both the sum of the third angle in the triangle and x has to be 180deg, as they sum to a half angle;

and the sum of angles in any triangle is 180deg.

We know that x = 180deg - (180deg - 28deg - 32deg) = 180deg - 180deg + 28deg + 32deg = 60deg

Also, note that x is drawn as smaller than a right angle. Unless the picture was made specifically to confuse us, we know that the only answer could be B.

Answer:

The exterior angle measures 60°

Step-by-step explanation:

Using the angles we already have we can determine that the missing interior angle is 120 since the interior angles of a triangle add up to 180°. So the missing interior and and the missing exterior angle are supplementary meaning they add up to 180. so 180-120=60°

Determine which system of equation has (-3,19) and (4,-23) as a solution?
grandymaker [24]

Answer:

y=6x+1

Step-by-step explanation:

First you must find the slope of the two points...

\frac{4--3}{-23-19} which then would equal 6

Then you take the slope and put into point-slope form

(y-y1)=m(x-x1)...take one of the points that is given and plug it into this formula.

so I used (-3,19).

(y-19)=6(x--3)

I would then get y-19=6x+18

Add 19 to both sides and you will get y=6x+1

Create a 5th degree trinomial that has a constant term of 3.
erastovalidia [21]

Answer:

4x^5\:+\:9x^2\:+\:3 is a trinomial having three terms, with degree 5 and the constant term '3'.

Step-by-step explanation:

Considering the trinomial

4x^5\:+\:9x^2\:+\:3

As the polynomial contains 3 terms, so it is a trinomial.

As the highest power of the variable 'x' is 5, so the degree of this polynomial is 5.

Any term with no variable is called a constant term. so, 3 is a term with no variable. Therefore, the constant term is 3.

Therefore, 4x^5\:+\:9x^2\:+\:3 is a trinomial having three terms, with degree 5 and the constant term '3'.

Answer:

502 m²

Step-by-step explanation:

We require to find b before calculating the surface area.

The volume (V) of a cuboid is calculated as

V = lbh ( l is length, b is breadth and h is height )

Here V = 510, l = b, b = 10 and h = 3, thus

b × 10 × 3 = 510

30b = 510 ( divide both sides by 30 )

b = 17

--------------------------

The opposite faces of a cuboid are congruent, thus

top/bottom area = 2(17 × 10) = 2 × 170 = 340 m²

front/back area = 2(17 × 3) = 2 × 51 = 102 m²

sides area = 2(10 × 3) = 2 × 30 = 60 m²

Surface area = 340 + 102 + 60 = 502 m²
