Answer: 6
Step-by-step explanation:
From the question, a base angle of isosceles triangle is 30°.We are also informed that one of the legs is 12. The altitude is opposite to the angle having a measure of 30°. The hypoteneous in the right angled triangle which is formed by drawing the altitude is 12. This will be calculated as:
Sin = opposite/hypotenuse
Sin 30°=length of the altitude/12
Note that sin 30° = 0.5
0.5 = length of the altitude/12
length of the altitude = 12 × 0.5
Hence, length of altitude = 6
Answer:

Step-by-step explanation:
We have

Put the coordinates of the given points and check the inequality:
For (0; 5) → x = 0; y = 5

For (2; 4) → x = 2, y = 4

For (1; 3) → x = 1, y = 3

The answer is d he traveled 198 miles over the span of 12 months driving to his friends house.
A quadrilateral that has all congruent sides and all right angles is known as a square.
Given is a quadrilateral with all right angles and congruent sides.
<h3>What is a Quadrilateral?</h3>
A four-sided polygon having four sides and four corners is referred to as a quadrilateral in geometry .
<h3>What are Congruent sides?</h3>
Congruent sides refers to a figure's sides being equal to one another.
We know that,
A square is a quadrilateral with angles that are each 90 degrees.
Additionally, a square has four equal sides, making it a quadrilateral having all sides congruent.
As a result, a square is a quadrilateral with congruent sides and all right angles.
