Answer: Product of powers
---
The product of powers rules basically says that two powers, let's call them a^{m} and a^{n}, with the same base (a) multiplied together equals a^{m+n}.

In your problem you can see that a^{2} and a^{3} are being multiplied together and the exponents are being added, which is what the "product of powers" law says.

Each base angle of an isosceles triangle measures 55° 30'. Each of the congruent sides is 10 centimeters long. Estimate the foll
kogti [31]

Answer:

55 deg 30 Minutes = 55.5 degrees  

sin = opp/hyp  

sin(55.5) = altitude/10  

Altitude = 10*sin(55.5)  

Altitude = 10 * sin(55.5) = 8.241261886  

Rounded to nearest 10th  

Altitude = 8.2 cm  

b. for base use Low of Cosines  

Let C = base  

Side A and B = length 10 Cm  

c^2 = 2*a^2 -2a^2*cos(<C)  

<C = 180 - 2*55.5 = 180 -111 = 69 degrees  

c = sqrt ( 2a^2 - 2a^2*cos(<C)  

c = sqrt ( 2*100- 200*cos(69))  

c = sqrt (200 - 200*cos(69) ) = 11.32812474  

Answer base  

c = 11.3 cms  

c.  

Area = (1/2)*b * h  

Area = (1/2)*(answer a * answer b)  

Area = (1/2)* 11.32812474* 8.241261886 = 46.67902132  

Area = 46.7 (rounded)  

Area = ( 1/2) * a*b*sin(<C) = (1/2)*10*10*sin(69) =  

Area = 50* sin(69) = 46.67902132  

Area = 46.7 (rounded)
