Answer:
xº=71º
Step-by-step explanation:
Take the triangle BDH
Once the sum of interior angles of a triangle is 180º:
40º+31º+yº=180º
71º+yº=180º
yº=109º
Once yº and xº are supplementary angles (add up to 180º):
yº+xº=180º
109º+xº=180º
xº=71º
Answer:
13 inches
Step-by-step explanation:
Perimeter is all the sides added so your equation would be 8+8+x+x=42 then you combine like terms. 16+2x=42. Next you would isolate the variable 2x=26 and the divide the 2 on both sides and you get x=13. Meaning your width is 13 inches long
