explanation is on the fig above
The answer is A (a mountain climber descending a mountain. This sis the answer because it is the only option with a decrease. When something decreases, a negative value (a number) represents the amount it decreased
Midpoint is (X1+X2)/2 and (Y1+Y2)/2. Therefore it would be (10+8)/2 Which is 9.
And (2-3)/2 which is -1/2. THE MIDPOINT WOULD BE (9,-1/2)
Step-by-step explanation:
x+100°=180°{being straight angle}
x=180-100
x=80°
again,
45°+x+y=180°{sum of angle of triangle}
45+80+y=180
y=180-125°
y=55°
hope it helps.
Answer:
