Answers

Answer:if a triangle is a right triangle, then the sum of the squares of the lenghts of the legs is equal to the square of the length of the hypotenuse.

- a property of all triangles with a right-angle (an angle of 90°)

Step-by-step explanation:

Zach is trying to find out the hypotenuse value of the right-angle triangle.

What is the right triangle?

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

The Pythagorean theorem states that "in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides".

Zach is most likely trying to find the length of the hypotenuse of a right triangle, which is the side opposite the right angle, given the lengths of the other two sides.

In this case, given 32 inches, 20 inches, and 20 inches values, he's trying to find out the hypotenuse value of the right-angle triangle.

Step-by-step explanation:

The measure of two exterior angles from the given figure are 60° and 90°.

What is sum of exterior angles of polygon?

An exterior angle is an angle which is formed by one of the sides of any closed shape structure such as polygon and the extension of its adjacent side. The sum of the measures of the exterior angles of a polygon is equal to 360 degrees, irrespective of the number of sides in the polygons.

From the given figure, the exterior angles are 70°, 2x°, 65°, 75° and 3x°.

Here, 70°+2x°+65°+75°+3x°=360°

210°+5x°=360°

5x°=150°

x=30°

So, 2x=60° and 3x=90°

Therefore, the measure of two exterior angles are 60° and 90°.

As A has angles 90,25 and 65 and B has angles 90,45 and 45, there are no two pairs of angles that are similar. Also as the angles are not equal the sides can't also be equal. So none of the above three methods are applicable here.

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

from the given table, we get,

total number of sample space is 6 x6 = 36.

now, we get, that, the number of getting sum less than 7 is 15

probability = no. of the event/ no. of total outcome

= 15/36

we get this,
