You can use the Pythagorean theorem, a^2+b^2=c^2, to solve this.
b= square-root of (c^2)-(a^2)
b= square-root of (9^2)-(2^2)
b= 8.77.... which in the exact form is square root of 77.
Matthew makes $15 money .
<u>Step-by-step explanation</u>:
- Total profit = $25
- Matthew gets 60% of the profit.
Therefore, the Matthew would get 60% of 25.
⇒ (60/100)
25
⇒ 0.625
⇒ $15
Answer:
c
Step-by-step explanation:
the perimeter of the sector
Answer:
In ∆ABD and ∆ACD
<BAD =<CAD ( each are half of <A )
<D=<D ( each equal to 90°)
AD = AD ( common)
So ∆ ABD is congruent to ∆ ACD.
Then AB =AC (by C.P.C.T)
Hence,∆ABC is an iso - sceles triangle.
