2. Classify the angle as acute, obtuse, right or straight.
O acute
O obtuse
Oright
straight

HELP ASAP

Answers

Answer:

Please include the details of the angle

Step-by-step explanation:

When the angle is 93 degrees, the the angle is a obtuse angle. option B is correct.

Given that the measure of angle A is 93 degrees, we can classify the angle as follows:

Angle A = 93 degrees

We know that if angle is less than 90 degrees, it is acute.

if angle is greater than 90 degrees, it is obtuse.

if angle is equal to 90 degrees, it is right angle.

Since the angle measures greater than 90 degrees, it falls within the range of an obtuse angle.

Therefore, the correct classification for angle A is obtuse.

“12 less than” would simply imply “subtract 12 from” the sum of 7 times a number. Let “x” represent the unknown number and multiply it by 7.

How do you find the height of a parallelogram without the area of it?

Answers

Answer:

See: https://brainly.in/question/12682555

Step-by-step explanation:

The link provided will take you to a differently worded explanation from another user.

You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:

c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.
