Answer:
Step-by-step explanation:
(10 - x^2)/b = b/2
Cross multiply
2(10 - x^2) = b^2
20 - 2x^2 = b^2
2x^2 = 20 - b^2
Dividing through by 2
x^2 = (20 - b^2)/2
√x^2 = √(20 - b^2)/2
x = √(20 - b^2)/2
Answer:
∠4 and ∠12
A is correct
Step-by-step explanation:
Parallel lines r and s are cut by two transversals, parallel lines t and u
r || s and t || u
We are four parallel line. Two parallel line cuts two another parallel line.
Angle 8 is form by intersection of s and t line.
Corresponding angle: When two parallel lines are crossed by transversal line, the angles at matching corners are called corresponding angles.
For angle 8, t || u with s is transveral line.
Thus, ∠8 = ∠12 (By definition of corresponding angle)
For angle 8, s || r with t is transveral line.
Thus, ∠8 = ∠4 (By definition of corresponding angle)
Hence, ∠4 and ∠12 are corresponding angle of ∠8
$20
I got it by dividing 12 tickets÷3 which equals 4. Then I multiplies 4×$5= $20
You would have to divide $16.76 by 4 to find out how much 1 gallon costs and after that multiply the amount a gallon costs by 7 to get your answer
