Find the measure of the unknown angle

97 degrees

Step-by-step explanation:

180 - 83 + 97

∠? =97°

Step-by-step explanation:

because the 2 lines are paralel the 83° angle and the missing angle are suplementary angles so they add up to 180°

?= 180-83=97°

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
