they add up to 180 so it depends. you have to know one of the measures
An angle which has measure between 90 degrees and 180 degrees is an obtuse angle.
Complementary.
it should be 169
Let the angle = θLet the height = aLet the base = b* means multiplied byIf the angle touches the base:tanθ = a/bb = a/tanθIf the angle touches the height:tanθ = b/ab = a*tanθWhen transferring the second line of working (b= ...) into a calculator, replace a with the height and θ with the angle. The answer will be b.
supplementary angles
Draw angle C and bisect it into A & B.
they add up to 180 so it depends. you have to know one of the measures
The transitive property is if angle A is congruent to angle B and angle B is congruent to angle C, then angle A is congruent to angle C.
The angles are supplementary if they have a sum of 180 degrees.

for a+ NEVERIn a parallelogram opposite angles are equal. Thus angle c = angle a = 40o.The sum of all the angles in a quadrilateral is 360o, so:angle a + angle b + angle c + angle d = 360o=> 40o + angle b + 40o + angle d = 360o=> angle b + angle d = 280o.
right angle
Angle b is acute angle, if any angle less than 90 degrees then it is called acute angle if more than 90 degrees then it is obtuse angle if it is equal to 90 degrees then it is right angled
angle B and angle D are supplements, angle B is congruent to angle D, angle A is congruent to angle A, or angle A is congruent to angle C
An angle which has measure between 90 degrees and 180 degrees is an obtuse angle.
The second angle? angle B?
