The question is: list the pairs of congruent angles and the extended proportion that relates the corresponding sides for the similar polygons.

Since we know that ΔCAB ~ Δ WVT

We have the following pairs of congruent angles:

∠CAB ≅ ∠WVT

∠CBA ≅ ∠ WTV

∠ACB ≅ ∠VWT

The porportion of the corresponding sides:

AB/VT = CA/WV = CB/WT

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
