Calculate the missing angle and give a reason for your answer

Vanyuwa [196]

Step-by-step explanation:

the triangle is an isosceles triangle hence the base angles are equal

sum of angles in a triangle is 180°, therefore, the top angle =180-(62+62)

the top angle =56°

h°= the top angle because alternate angles are equal

hence, h=56°

Using number lines 80 is 25% of what number

Goshia [24]

25% can be made in to 100% by multiplying it by 4.

Therefore, we can find the answer by multiplying 80 by 4.

(6, -12). (15. -3)<br> Find the slope

Allisa [31]

Answer:

The slope is 1.

Step-by-step explanation:

A first order function has the following format

$y = ax + b$

In which a is the slope

(6, -12).

This means that when $x = 6, y = -12$

$y = ax + b$

$-12 = 6a + b$

(15. -3)

This means that when $x = 15, y = -3$

$y = ax + b$

$-3 = 15a + b$

We have to solve the following system of equations:

$-12 = 6a + b$

$-3 = 15a + b$

We have to find a

In the second equation i will write as:

$b = -3 - 15a$

Replacing in the first

$-12 = 6a + b$

$-12 = 6a - 3 - 15a$

$-9 = -9a$

$9a = 9$

$a = \frac{9}{9}$

$a = 1$

The slope is 1.

A lottery game requires that a person select in uppercase or lowercase letter followed by two different two-digit numbers (where

Irina-Kira [14]

Using the Fundamental Counting Theorem, it is found that there are 416,520 ways to fill out a lottery ticket.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with $n_1, n_2, \cdots, n_n$ ways to be done, each thing independent of the other, the number of ways they can be done is:

$N = n_1 \times n_2 \times \cdots \times n_n$

In this problem:

First, one uppercase or lowercase letter is chosen, there are 26 of each, hence $n_1 = 52$ .

Then, two different two-digit numbers are chosen, and there are 90 of them, hence $n_2 = 90, n_3 = 89$ , as the third digit has to be different of the second.

Then:

$N = n_1n_2n_3 = 52(90)(89) = 416520$

There are 416,520 ways to fill out a lottery ticket.
