Step-by-step explanation:
Answer:
m ∠S = 43°
Step-by-step explanation:
Exterior angle = Sum of opposite interior angles
(6x)° = 77° + (2x + 3)°
6x = 77 + 2x + 3
6x - 2x = 77 + 3
4x = 80
x = 20
m ∠S = (2x + 3)° = 2(20) + 3 = 40 + 3 = 43°
A. 3(x + 3) > -3(2 + x) SOMETIMES TRUE
3(x + 3) > -3(2 + x) |use distributive property a(b + c) = ab + ac
3x + 9 > -6 - 3x |add 3x to both sides
6x + 9 > -6 |subtract 9 from both sides
6x > -15 |divide both sides by 6
x > -15/6
x > -2.5
B. 9 - x - 5 < - x + 4 NEVER TRUE
9 - x - 5 < - x + 4
4 - x < - x + 4 |add x to both sides
4 < 4 FALSE
The answer would be false
Not sure but im guessing 6 inches
