Plss help me and explaim too​

Mathematics
1 answer:
masya89 [10]3 years ago

Answer:

a = b = 1

Step-by-step explanation:

The triangles are similar thus ratios of corresponding sides are equal, that is

\frac{10}{2} = \frac{5}{b} ( cross- multiply )

10b = 10 ( divide both sides by 10 )

b = 1

and

\frac{10}{2} = \frac{5}{a} ( cross- multiply )

10a = 10 ( divide both sides by 10 )

a = 1

Thus a = 1 and b = 1

now that we know how long each one is, let's plug those in Heron's Area formula.

What must be the value of n ?
jarptica [38.1K]

Answer:

Since we have a^7 on the Numerator and after simplification... No "a" was left in the expression. It simply means that all a's in the numerator was eliminated and 2a's were left in the denominator.

To eliminate a^7 and still have 2a's as a remainder in the denominator... 'n' must be equal to 9

So

n=9
