Answer:
x=4
Step-by-step explanation:
7-2x=2(x-4)-1
7-2x=2x-8-1
7-2x=2x-9
7+9=2x+2x
16=4x
x=4
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
