The measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles.
75-28=47
No solution as they are parallel lines. so, inconsistent
X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8
Answer:
3520
Step-by-step explanation:
33-11=22
40 times 22=880
