x=78

Step-by-step explanation:

The value of x from the triangle is given by the equation x = 78°

What Is an Isosceles Triangle?

A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.

In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle

The three types of Isosceles Triangles are :

Isosceles acute triangle

Isosceles right triangle

Isosceles obtuse triangle

Given data ,

Let the triangle be represented as ABC

Now , the measure of angle ∠A = 24°

It is an isosceles triangle with ∠B = ∠C

So , the measures of the two angles are the same

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

Substituting the values in the equation , we get

x + x + 24° = 180°

On simplifying the equation , we get

2x = 156°

Divide by 2 on both sides of the equation , we get

x = 78°

Hence , the measure of x = 78°

A college student takes the same number of credits each semester. She had 12 credits when she started, and after
semesters, she had 96 credits.
Which of these expresses the rate at which she is earning credits?

Answers

Answer:

The student obtains his 12 credits each semester during 8 semesters.

Step-by-step explanation:

Since a college student takes the same number of credits each semester, and she had 12 credits when she started, and after

semesters, she had 96 credits, to determine the rate at which she is earning credits, the following calculation must be performed:

96/12 = 8

Thus, the student obtains his 12 credits each semester during 8 semesters.

What is the explicit rule for the arithmetic sequence? 20.5, 16, 11.5, 7, 2.5, ...

Answers

Answer:

To determine the explicit rule for the arithmetic sequence of 20.5, 16, 11.5, 7, 2.5, ..., the following logical reasoning must be performed:

20.5 - 16 = 4.5

16 - 11.5 = 4.5

11.5 - 7 = 4.5

7 - 2.5 = 4.5

Thus, the explicit rule of the arithmetic sequence is that the numbers are gradually subtracted by 4.5, with which the next number of said sequence would be -2.

Let's reduce the numbers and then we'll reduce exponents of c.

[tex]\frac{-60}{-15}=4[/tex]

Using exponent rules, we simply subtract the exponent from the top and the exponent from the bottom.
