Given STU and DEF what is the m
Sonja [21]

Answer:

m<E = 105°

Explanation:

The ratio of the corresponding side lengths of ∆STU and ∆DEF are equal. That is:

\frac{ST}{DE} = \frac{TU}{EF} = \frac{SU}{DF} = \frac{15}{6} = \frac{10}{4} = \frac{20}{8} = 2.5.

According to similarly theorem, if two ∆s are similar, the ratio of their corresponding lengths would be the same. Therefore, ∆STU is similar to ∆DEF.

Since ∆STU ~ ∆DEF, their corresponding angles are congruent. That is:

<S ≅ <D, this means both are 29° each.

<T ≅ <E, this means they are both equal

<U ≅ <F. this means both are 46° each.

Thus:

m<E = 180 - (m<D + m<F) (sum of ∆)

m<E = 180 - (29 + 46) (substitution)

m<E = 180 - 75

m<E = 105°

Nostrana [21]

Answer:

Stabilizing natural selection keeps gene frequencies constant in a population. The normal, most common traits are selected for and preserved so only a limited amount of evolution occurs and species can remain unchanged even over long periods of time.
