4.2 is the answer of this question you are asking ✌️
Answer: SAS
Step-by-step explanation:
The Side Angle Side (SAS) postulates that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent
16×14×2+16×18×2+14×18×2=1528
1:24 and 2:20 and 3:30 and 4:16 and 5:12
We have that
cos A=0.25
so
A=arc cos (0.25)-------> using a calculator----> A=75.5225°
Round to the nearest hundredth-----> A=75.52²
the answer is
the option <span>75.52°</span>
