Answer:
it would be 53
Step-by-step explanation:
Commutative Property is used here
Using the formulas
:
A=2AB+(a+b+c)h
AB=√(s(s﹣a)(s﹣b)(s﹣c)
)
s = (a+b+c) / 2
Solving for A:
A=ah+bh+ch+1
/2 √(﹣a∧4+2(ab)∧2+2(ac)∧2﹣b∧4+2(bc)∧2﹣c∧4)
=2·1.7+3·1.7+2·1.7+1
/2· √(﹣2∧4+2·(2·3)∧2+2·(2·2)∧2﹣3∧4+2·(3·2)∧2﹣24)
≈15.86863
Angle C because they are the same line
It is 8 because you would do 9x8=72
