Can a triangle have two obtuse angles? explain

Remember that an obtuse angle measures greater than 90°.

A triangle never contains two obtuse angles.

If a triangle were to contain two obtuse angles, then there would be two angles in the triangle that measure greater than 90°, so the sum of these two angles would be greater than 180°. Since we know that the sum of all three angles in a triangle must be exactly 180°, it doesn't make sense that the sum of two of the angles would already by greater than 180°.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
