Step-by-step explanation:
I think it will work if you Divide 54 over 12 = 4.5
Answer:
∠ SPQ = 75°
Step-by-step explanation:
The sum of the 4 angles in a quadrilateral = 360°
Subtract the sum of the 3 angles from 360 for ∠ SPQ
∠ SPQ = 360° - (90 + 74 + 121)° = 360° - 285° = 75°
First, we can do distributive property.
-3(n + 8) = 15
-3 x n = -3n, -3 x 8 = -24
So we have, -3n + -24 = 15
Minus -24 on both sides of the equal sign.
-3n + -24 - -24 = 15 - -24
-3n = 39
Divide 3 on both sides.
-3n/-3 = 39/-3
n = -13
Hope i helped!! :D
