Meridians and circles of latitude (parallels) will meet at an angle of 90 degrees at the equator only. All other crossings will not be 90 degrees as they converge to the two poles.
To correct the previous answer: All meridians crossing parallels are not at 90 degrees due to the curvature of the spherical triangle's three sides. However, they will all cross at 90 degrees as viewed each from a specific point in space which would be perpendicular to the earth's N-S axis and directly over (in line) with the meridian.

What are the other angles of a parallelogram when one interior angle is 27.5 degrees?
The other 3 angles are 27.5 degrees, 152.5 degrees and 152.5 degrees because opposite angles are equal in a parallelogram and its 4 interior angles add up to 360 degrees.
What size are the angles inside a pentagon when two are 85 degrees and 95 degrees with the other angles all being equal in size?
The other three angles will each measure 120 degrees.
If three angles in a hexagon measure 140 degrees what are the measures of the other three angles?
55 degrees
If one angle of a parallelogram measures 40 degrees and another angel measures 140 degrees what are the measures of the other two angles?
The other two angles are also 40 degrees and 140 degrees.
Two angles that add to 180 degrees?
When two angles add up to 180 degrees, they are supplementary to each other.
