The vertex where the two triangles touch forms a pair of vertical angles, so that the angles on opposites sides of the vertex are congruent. You're shown that two legs of both triangles are congruent. All this tells you that the two triangles are isosceles, and furthermore that they are similar because of the congruence of their "base" angles.
This means
T=21+4.5X
21 is the original temp.
4.5 is the constant rate I got when I subtracted 75-21=54 then divided 54/12min=4.5.
75 =21 + 4.5(12)

answer to the problem is x=2/3
Answer: <u>£21007.22</u>
Step-by-step explanation:
First, find the interest amount using the formula SI = (P × R × T) / 100.
- SI = interest amount
- P = principle amount = £18790
- R = interest rate(in percentage) = 5.9
- T = time(in years) = 2
SI = (P × R × T) / 100 = (18790 × 5.9 × 2)/100 = 221722/100 = £2217.22
The total amount = principle amount + interest amount
= £18790 + £2217.22 = <u>£21007.22</u>
