Answer:
an =a1+(n−1)d
Step-by-step explanation:
B. <span>She is correct. The remaining angle of the triangle measures less than 90 degrees.</span>
X² - 4x + y² - 8y = 5
Complete the square:
x² - 4x + (4) + y² - 8y + (16) = 5 + (4) + (16)
→ (x - 2)² + (y - 4)² = 25
Center: (2,4)
radius: √25 = 5
Let Sara weight =x+25
amber wiegh =x
x+25+x=205
x= 90
Sara weight is 90+25= 115
