Answer:

16.2

Step-by-step explanation:

Since, if the sum of two angles is 90° then they are called complementary angles.

Here, the given angle is 73.8°,

Let x be the complementary angle of 73.8°,

Thus by the above definition,

x + 73.8° = 90°,

By subtraction property of equality,

⇒ x = 16.2°,

Hence, the complementary angle of 73.8° is 16.2°.

Which binomial is a factor of 9x2 – 64? 3x – 8 9x – 32 3x 32 9x 8

aalyn [17]

The binomial factor of the equation $\rm 9x^2 -64$ is 3x-8.

<h3>What is a binomial factor?</h3>

The algebraic expression which contains only two terms is called binomial. It is a two-term polynomial. Also, it is called a sum or difference between two or more monomials.

Factoring binomials means breaking down a binomial expression into its simplest form.

Binomials are algebraic expressions with two terms.

The given binomial is;

$\rm 9x^2 -64$

The binomial is determined in the following steps given below.

$\rm =9x^2 -64\\\\= (3)^2x^2-8^2\\\\= (3x)^2-8^2\\\\= (3x-8)(3x+8)$

Hence, the binomial factor of the equation $\rm 9x^2 -64$ is 3x-8.

A team fixed a road that was 4,800 m long. After working for 30 days, there was still 1,440 m of the road left to fix. On averag

arlik [135]

The total of the road is 4800 m long. 4800-1440=3360m
We subtract what they have yet to cover from the total to get what they have covered.
So in 30 days they covered 3360 metres.
3660/30 (3660 is divided into 30 equal groups) = 122m
On average they covered 122 metres per day.

Hallar el valor del cateto a

love history [14]

Answer:

a = 5.07

Step-by-step explanation:

Here, we want to get the value of the side marked a

What we have is a right triangle

so, to find the value of a, we are to use the correct trigonometric ratio

The angle given faces a, which makes a the opposite

the side measure faces the right angle and that makes it the hypotenuse

The trigonometric ratio that connects the two is the sine

The sine is the ratio of the opposite to the hypotenuse

mathematically;

sine 25 = a/12

a = 12 * sine 25

a = 5.07

How many 10-digit ternary strings are there that contain exactly two 0s, three 1s, and five 2s?

Svet_ta [14]

There are $\dbinom{10}2$ ways of picking 2 of the 10 available positions for a 0. 8 positions remain.

There are $\dbinom83$ ways of picking 3 of the 8 available positions for a 1. 5 positions remain, but we're filling all of them with 2s, and there's $\dbinom55=1$ way of doing that.
