Answer:
3. 63°
4. x = 13
Step-by-step explanation:
3. The exterior angle is equal to the sum of the opposite interior angles.
118° = (4x +7)° + (6x -9)°
120 = 10x . . . . . . . . . divide by °, add 2
12 = x
m∠K = (6x -9)° = (6·12 -9)°
m∠K = 63°
__
4. Corresponding angles are congruent, and the sum of angles in a triangle is 180°.
74° + (5x)° + (3x+2)° = 180°
8x = 104 . . . . . . . . . . . . . . . divide by °, subtract 76
x = 13 . . . . . . . . . . . . . . . . . .divide by 8
X = -6 + y...so we sub in -6 + y for x in the other equation
x - 3y = 28
-6 + y - 3y = 28
-2y - 6 = 28
-2y = 28 + 6
-2y = 34
y = -34/2
y = - 17
x = -6 + y
x = -6 - 17
x = - 23
solution is (-23,-17)
