Answer:
Step-by-step explanation:
A+B+C = 180°
A ≤ B ≤ C
B = A+9
C = 3A+26
A+B+C = A + (A+9) + (3A+26) = 5A + 35° = 180°
5A = 145°
A = 29°
B = A+9 = 38°
C = 3A+26 = 113°
Step-by-step explanation:
Add 1 to both sides
Multiply both sides by 4
Take the square root of both sides
Subtract 5 from both sides

Is that a ratio? then i’ll answer it
Answer:
x=10
Step-by-step explanation:
We first need to combine like terms
76-4x=36 We will then use inverse operations to find x
-4x=-40 Continue using inverse operations
x=10
