Answer:
180
Step-by-step explanation:
A=1/2*b*h
A= 1/2*8*25
180
Use the half angle identity, tan157.5=(1-cos315)/sin315
cos315=cos(-45)=√2/2, sin315=-√2/2
tan157.5=(1-√2/2)/(-√2/2)=(2-√2)/(-√2)=(2√2-2)/(-2)=1-√2
Answer:
A or B
Step-by-step explanation:
No it’s not as its not constant and its a fraction
