Answer:
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(:
