yes im pretty sure you can, a trapesium can have two obtuse angles (obtuse - above 90 degrees. acute - below 90 degrees) hope this helped :) xx

Share If each quadrilateral below is a rhombus, find the missing measures UV: 8 and WX=5?
Anything below 90 degrees
Well 90% is a complete right angle so... it is obtuse if it is over 90% and if it is below 90% it is an acute angle <3
an acute angle doesn't have an exact measurement, but it is lower than 90 degrees. So any angle below 90 degrees is an acute.
It would be a concave quadrilateral The link below has some pics.

An angle that is measured at 199 degrees would be considered an "Obtuse" angle. This is because the degrees measurement exceeds 90. Anything below 90 would be considered acute.
The sum of the three angles of a triangle is 180 degreesIf it is a right angle triangle one angle must be 90 degreesAll u have to do is 180-90- (the angle u already know)= unknown angle (third angle)Just like regular numbers, angles can be added to obtain a sum. Sometimes we can determine a missing angle because we know that the sum must be a certain value. Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees.If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry. We can use this idea to find the measure of angle(s) where the degree measure is missing or not given.Sample AIn triangle ABC below, angle A = 40 degrees and angle B = 60 degrees. What is the measure of angle C?We know that the sum of the measures of any triangle is 180 degrees. Using the fact that angle A + angle B + angle C = 180 degrees, we can find the measure of angle C.angle A = 40angle B = 60angle C = we don't know.To find angle C, we simply plug into the formula above and solve for C.A + B + C = 180C = 180 - A - BC = 180 - 40 - 60C = 80To check if 80 degrees is correct, let's add all three angle measures. If we get 180 degrees, then our answer for angle C is right.Here we go:40 + 60 + 80 = 180180 = 180...It checks!You don't always have to plug in those values to the equation and solve. Once you're comfortable with this sort of problem you'll be able to say "okay, 40 + 60 =100, so the other angle has to be 80!" and it's much quicker.Sample BIf a triangle is equiangular, what is the degree measure of each of its angles?Remember, all angles of an equiangular triangle have equal measure. Let x = the degree measure of each angle. Triangles have three vertices and so we will add x THREE times.We have this:x + x + x = 1803x = 180x = 60Makes sense, right? If all the angles are equal, and they add up to 180, then it has to be 60 degrees!NOT USFULL TO LONG BIA
