You measure it with a protractor.
I need to know how to find each angle measured to the first degree. Such as: Sin B= 0.4848
dont know
Height and degree only give the base in right triangles, because in that case you'd know angle-side-angle (because you know one is 90 degrees).
72 degrees
Well, honey, a 131 degree angle is an angle that measures 131 degrees. It's bigger than a right angle but smaller than a straight angle. So, if you ever need to measure something at 131 degrees, now you know what you're dealing with.
asuming you know how to construct a 60 degree angle, you would start by drawling a basic construction line an then make your angle bisecter with breaks the angle into 30 degree angles. then create another angle bisector for 30 degrees breaking it into 15 degree angles. then do the same with the 15 degree angle. your drawling sould have three angle bisectors for each angle. to get your answer of 22.5 degress angle, simply add the 15 degree angle you drew with the 7.5 angle you got from spliting the 15 degree angle in half its hard to explain without drawing it out..... hope this helps
The complement of a 55 degree angle is a 35 degree angle
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.
