The commutative propertyof addition says, "that you will get the same answer whether you are adding 1+2 or 2+1. this also works for 2 or more number."
I hope this helps!
Answer:
30 cm
Step-by-step explanation:
<u>Area of a triangle formula:</u>
A = 0.5bh
<u>Given:</u>
b = 12
c = 5
<u>Work:</u>
A = 0.5bh
A = 0.5(12)(5)
A = 6(5)
A = 30
Not completely sure on the symbols, but I think it is 5 x ( 22 - 9 x 2 ) - 2 ( 3 x 2 x 4 ) x 7 = 136. It doesn't really match the answers, so my advice is that you use a calculator for this one, or as the person/teacher who gave you the problem how to solve it.
Both of the missing angles are 45*.
Hope I helped. :)
Well, to solve, you would subtract 8 from both sides, which means x would end up equaling 32.
X=32
