Hello again Charlesbabegirl! :)
First of all, let's say that the sum of all internal angles of a triangle is always 180°
This means that if you add up angles A, B and C you get 180 but we should find first the value of x by setting up a proportion of this type:
A + B + C = 180
12x + 12 + 15 + 3x + 18 = 180
Move all the known terms (those that don't have x) to the right with changed sign.
12x + 3x = 180 - 12 - 15 - 18
15x = 135
Divide both terms by 15
x = 9
Then plug the value of x...
m∠A = 12(9) + 12 = 108+12 = 120°
m∠C = 3(9) + 18 = 27 + 18 = 45°
Hope I helped and let me know if I was right!
Answer:
Pretax cost of debt is 5.94%
After tax cost of debt is 4.63%
Step-by-step explanation:
The pretax cost of the debt is the yield to maturity on the debt issuance,which can be computed using the rate formula in excel:
=rate(nper,pmt,-pv,fv)
nper is the number of semi-annual interest payments payable by the bond from year 3 onward ,that is the number of years to maturity 12*2=24
pmt is the semi-annual interest payable by the bond issuer which is face value of the bond ,$1000*5%/2=$25
pv is the current price of the bond which 92% of face value i.e 92%*$1000=$920
fv is the face value of the bond at $1000
=rate(24,25,-920,1000)
rate=2.97%
the rate calculated is a semi-annual rate,annual rate =2.97%*2
=5.94%
The pretax cost of debt is 5.94%
After tax cost of debt=pretax cost of debt*(1-t)
t is the tax rate of 22%
after tax cost of debt =5.94%*(1-22%)
=4.63%
The perimeter would be 228 inches
Hope this helped =)
I graphed it on desmos, hope this helps a little :)
