Fill in the missing sign (?) according to the diagram:
Angle BAC ? angle E
Fist let's look at triangle ABC, remembering that the sum of angles in a triangle equals 180 degrees.
In triangle ABC, we are given two angles: 40 and 90.
Therefore, we can calculate BAC as follows:
Now let's look at angle E, noting that it is greater than 90 degrees.
Therefore:
Indicates which angle is greater
Look at the angle markings in the diagram! The curved lines with "40" show you exactly which angles measure 40°. One is at vertex B and one is at vertex C.
Angle E appears to be an obtuse angle based on the diagram. It looks wider than a right angle (90°), making it larger than our calculated angle BAC of 50°.
Double-check your arithmetic: . Remember the right angle (square symbol) is 90°, not one of the 40° angles!
Absolutely! Many triangles can share the same angle measures. What matters here is comparing the specific angles BAC and E from this particular diagram.
Think of it this way: if you walk around any triangle and return to your starting point, you've made exactly one complete turn = 360°. The interior angles are half of that!
