Answer:
13 = m
Step-by-step explanation:
I do not know what that nine is doing there, but you just simply evaluate to arrive at your answer.
Answer:
I think it is 370
Step-by-step explanation:
Since you’re already given one of the sides of the triangles as well as the triangle’s hypotenuse, you’ll want to find the third side to find the area.
To find the third side length, we’ll use the Pythagorean Theorem:
a^2 + b^2 = c^2
“a” and “b” can be used interchangeably, so we can substitute the known side length of 7 cm into “a”. 25 cm substitutes for “c” since it’s the hypotenuse.
(25)^2 - (7)^2 = c^2
c = 24
Area of triangle = (1/2)bh, where “b” and “h” are interchangeable.
Area of triangle = (1/2)(24)(7) = 84 cm^2
Answer:
the computed value gets larger
Step-by-step explanation:
Step-by-step explanation:
the correct formula for this is the heron's formula
which states that s=√s(s-a)(s-b)(s-c). Where s is a+b+c all divided by 2
s=√(13.5-12)(13.5-9)(13.5-6)
s=√(1.5)(4.5)(7.5)
s=√50.625
s= 7.11 or 7 to the nearest square unit
