Well since there are 13 cards per suit, you start off with 13 cards. then since there are 4 suits that are able to be used, but one of those 4 is the spades suit. so you have 3 6's that can be used besides the spades. so you are left with a total of 16 cards that fit the description.
The sum of angles in any triangle is 180 degrees.
It is given <1+<3=154 degrees.
<1+<2+<3=180
Or <1+<3+<2=180
Substituting <1+<3=154 we have
154+<2=180
Subtracting 154 both sides <2=180-154
<2= 26 degrees
First option is right answer.
Two Angles are Supplementary when they add up to 180 degrees
Two Angles are complementary when they add up to 90 degrees
Given <1+<3 =154 So they are neither complementary or supplementary.
