Answer:
B) Subtraction Property of Equality
Step-by-step explanation:
To get m∠B=77º, the problem subtracted 103º from both sides of 103º+m∠B=180º.
The Subtraction Property of Equality states that if x=y, then x-a=y-a.
In this case x=103º+m∠B, y=180º, and a=103º.
Answer:
y= -2/8x + 3
Step-by-step explanation:
Answer:
193
Step-by-step explanation:
according to the question
w²=x²+v²-2xv.cos(<w)
w=√160²+150²-2.160.150.cos(77)°
w=√48100-48000cos(77°)
w=193
