A 155 degree angle is an angle that measures 155 degrees. It falls between 90 and 180 degrees, which means it's an obtuse angle. So, if you're ever in a situation where you need to identify a 155 degree angle, now you know it's just a fancy way of saying "more than a right angle, but less than a straight angle."
all angles greater then 90o are called obtuse angle
25 degrees
The complement of a 55 degree angle is a 35 degree angle
A 12 degree angle is an acute angle.
Cos(-155) = cos(155) = 1 - cos(180-155) = 1-cos(25).
180-25=155 answer:155
all angles greater then 90o are called obtuse angle
It is 110 degrees
It is an obtuse angle.
25 degrees
The complement of a 55 degree angle is a 35 degree angle
Oh, dude, it's like a piece of cake! So, a minor arc is like a slice of pizza, right? And the central angle is like the angle at the center of the pizza. If the minor arc is 155 degrees, then the central angle is also 155 degrees. Easy peasy, lemon squeezy!
A 90 degree angle is a right angle.
118 degree angle
A 22 degree angle is an acute angle
A 12 degree angle is an acute angle.
The supplementary angle to a 145 degree angle will be a 35 degree angle because 145 + 35 = 180.
