1/4 would be the answer. Let me explain why first. You have in total 4 numbers with different out comes when added together. So your equation will start out as 4² = 16 out of the 16 different factors you have 4 sets that equal 180°. Your new fraction would be 4/16 which can be divided by 4 to equal 1/4. Hopes that helps!
Answer: 30 inches.
Step-by-step explanation:
We need to use the formula for calculate the perimeter of a rectangle. This is:
Where "l" is the length and "w" is the width.
In this case, we know that the lenght and the width of this rectangle are:
Therefore, substituting values into the formula, we get that the perimeter of this rectangle is:
<span>3x-6y=18
x - 2y = 6
</span>if x = -4, then -4 - 2y = 6...-2y = 10, so y = -5
if x = -2, then -2 - 2y = 6...-2y = 8, so y = -4<span>
if x = 0, then -2y = 6.... y = -3
if x = 2, </span>then 2 - 2y = 6...-2y = 4, so y = -2
if x = 4, then 4 - 2y = 6...-2y = 2, so y = -1
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.
