Step-by-step explanation:

<u>Congruent Triangles</u>

The SAS Similarity Theorem states that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both triangles are congruent, then the two triangles are similar.

The triangles $\Delta LKN\ and\ \Delta KNM$ are congruent if the relation between LK and KN is the same as the relation between KN and MN, that is

$\displaystyle \frac{4}{2}=\frac{2}{MN}$

It means that

MN=1

Find the measure of

sergij07 [2.7K]

Answer:

∠ ABC ≈ 137.9°

Step-by-step explanation:

Using the Cosine rule in Δ ABC

cos B = $\frac{a^2+c^2-b^2}{2ac}$

with a = 89, b = 144, c = 65

cos B = $\frac{89^2+65^2-144^2}{2(89)(65)}$ = $\frac{7921+4225-20736}{11570}$ = $\frac{-8590}{11570}$ , thus

B = $cos^{-1}$ ( - $\frac{8590}{11570}$ ) ≈ 137.9° ( to the nearest tenth )
