Answer:
Step-by-step explanation:
1). By definition of an exterior angle of a triangle,
Measure of exterior angle of a triangle is equal to the sum of opposite two interior angles.
From the figure attached,
m∠4 = m∠1 + m∠2
2). Property of a triangle states that " sum of interior angles of a triangle is 180°"
Therefore, m∠1 + m∠2 + m∠3 = 180°
-0.33,-0.17,-1/2,0.25
3x+1=3x+1
0x=0
no solution
3x+1=3x+2
0×=1
3x+1=2x+1
x=0
X IS THE SOLUTION BTW
-68ft, or 68ft below sea level
-72+4=-68
