Step-by-step explanation: 3÷15=5
3÷5=1
3÷27=9
51.9
Radius = 1.9 in.
circumference = 11.94 in.
2x + 3 = 3x - 8
2x + 11 = 3x
3x = 33
x =11
Take the common denominator and divide by 3 then youll get 58
Answer:
x=4
Step-by-step explanation:
We are given that the triangles are congruent.
Specifically, the order of the letters gives that the angles ∠DAB and ∠CBA are corresponding parts of the two congruent triangles. Since corresponding parts of congruent triangles are themselves congruent, ∠DAB ≅ ∠CBA. Thus, m∠DAB = m∠CBA.
Given the expressions for the two angles, we can substitute into the equation, and solve for the requested variable.
