From the two right triangles, you can write the following equations using the Pythagorean theorem. Let's call that shared leg in the middle "y"
y^2 + b^2 = a^2
y^2 + c^2 = x^2
y^2 + b^2 = a^2
re-write this to get "y" alone for substitution.
y^2 = a^2 - b^2
substitute (a^2 - b^2) for y^2 in the other equation. y^2 + c^2 = x^2
a^2 - b^2 + c^2 = x^2
Now put in the values given for a,b,c to solve for x
(7.1)^2 - (5.6)^2 + (5.7)^2 = x^2
51.54 = x^2
square root
7.2 = x
add all amd divide by the 40 ???let me know if im wrong
Answer:
£10,737,418.24
Step-by-step explanation:
<u>Every day amount doubles:</u>
- March 1st = 1p= 2^0 p
- March 2nd = 2*1p = 2^1 p
- March 3rd = 2*2p = 2^2 p
- ...
- March 31st = 2^30 p = 1,073,741,824 p = £10,737,418. 24
