hi, first question's answer B.

because if you want to draw a triangle, there is have to be some rules. like can you draw a triangle 2,2,20? that could be impossible because all the edges have to intersect. think a triangle and it has 3 edges. they are A,B,C

if you wanna write random numbers, you have to do this.

A+B>C>|A-B|

A+C>B>|A-C|

C+B>A>|C-B|

soo, 7+11= 18 and 11-7=4

second question's answer is this:

60+x+32+90=180(if you wonder where is the 90 came from, the triangle's one side has square. that mean its 90°.

182+x=180

x=-2

if you have questions about these questions, you can ask me.

good luck(:
