Iteru [2.4K]

Step-by-step explanation:

Given : m∥n , ∠1= 50° , ∠2= 48° , and line s bisects ∠ABC

To prove = ∠3= 49°

Solution:

In figure, m∥n cut by traversal t.

So,  ∠DEF = ∠ABC(alternative exterior angles)

∠1 + ∠2 = ∠4 + ∠5

∠ABC = ∠1 + ∠2 = 50° + 48° = 98°

Also given that s bisect angles ∠ABC.

∠4 = ∠5

∠ABC = ∠4 + ∠5 = 98°

∠4 + ∠4 = 98°

2∠4 = 98°

∠4 = 49°

∠4= ∠3 = 49° (vertically opposite angles)

∠3 = 49° ,hence proved

A cabinet set was sold at RM 9500 after a markup of 6.5%. Find the original price and the markup amount.
LiRa [457]

Answer:

1) The original price is 8920 2) The mark up is 580

Step-by-step explanation:

!)We need to find out the initial price, suppose it is equal to 100 percents. The price was raised and it has reached 100+6.5= 106.5 percents . 106.5 percents from initial price is the new price (RM 9500). Find out the value of one percent

9500:106.5= 89.2 (approximately).

2)Then find the original price multiplying the value of percent by 100. 89.2*100= 8920 - initial price

3)Then mark up is a remainder between old price and new price . It is  9500-8920= 580.

One root of a third degree polynomial function f(x) is -5 + 2i. Which statement describes the number and nature of all
Sauron [17]

Answer:

f(x) has two imaginary roots and one real root.

Step-by-step explanation:

Complex roots:

I a complex number a + bi is a root of a polynomial, it's conjugate a - bi is also a root.

One root of a third degree polynomial function f(x) is -5 + 2i.

This means that -5 - 2i is another root of the polynomial, and thus, 2 of the roots are complex.

Third degree, so it has three roots, which means that the third root is real(not possible to have a complex root without it's conjugate), and thus, the correct answer is:

f(x) has two imaginary roots and one real root.
