Use the figure to find the measures of the numbered angles,
Galina-37 [17]

Given:

A figure in which a transversal line t intersect the two parallel lines a and b.

To find:

The measure of the numbered angles.

Solution:

If a transversal line intersect the two parallel lines, then

1. Corresponding angles are equal.

2. Alternate interior angles are equal.

3. Alternate exterior angles are equal.

Now,

m\angle 1+99^\circ=180^\circ              (Linear pair)

m\angle 1=180^\circ-99^\circ

m\angle 1=81^\circ

m\angle 2=99^\circ                         (Vertically opposite angles)

m\angle 3=\angle 1=81^\circ                (Vertically opposite angles)

m\angle 4=99^\circ                         (Corresponding angles)

m\angle 5=\angle 3=81^\circ                (Alternate interior angles)

m\angle 6=99^\circ                         (Alternate exterior angles)

m\angle 7=\angle 3=81^\circ                (Corresponding angles)

Therefore, \angle 1=81^\circ, \angle 2=99^\circ,\angle 3=81^\circ, \angle 4=99^\circ,\angle 5=81^\circ, \angle 6=99^\circ,\angle 7=81^\circ.

Polynomials!?!? What is the product of -2x^3+x-5 and x^3-3x-4... Is the product of -2x^3+x-5 and x^3-3x-4 equal to the product o
zaharov [31]
T<span>he product of -2x^3+x-5 and x^3-3x-4 would look like this before simplification:

-2x^6 + 6x^4 - 8x^3 + x^4 - 3x^2 - 4x - 5x^3 + 15 x^2 + 20

Now combine all the like terms.  For example, 6x^4 + x^4 = 7x^4.

Write the product in the simplest possible form, which involves combining like terms and arranging them in descending order by power of x.

ZanzabumX [31]

Answer:

  • 5. p - 0.15p

Step-by-step explanation:

Original price = p

Discount in every item = 15%

An item will cost :-

= p - (15% of p)

= p - 15p/100

= p - 0.15p
