Base angle theorem proves that
Answer:
x=-3
Step-by-step explanation:
Place like terms on the same side.
Keep in mind when a term is moved from its original position, it changes sign.
x+x=-3-3
2x=-6
x=-3

Answer:
4 out of 20 if I'm not mistaken
Step-by-step explanation:
Add all the numbers and then you get 20 and there are 4 yellow marbles so 4 out of 20
Area of square =6*6= 36 cm^2
Area of trapezoid =1/2( base1+base2)*height
base 1=7
base2=21-6=15
height=6
Area of trapezoid =1/2( 7+15)*6= 66
whole area = area of square + area of trapezoid= 36+66=102
Answer 102
