Omg yes it’s so good !!!!
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
Answer:
- 13
Step-by-step explanation:
To evaluate (g ○ f)(3), evaluate f(3) then use this value to evaluate g(x)
f(3) = 3 - 7 = - 4, then
g(- 4) = 4(- 4) + 3 = - 16 + 3 = - 13

There are special properties to certain right triangles.
A 3-4-5 triangle will always be a right triangle. 9 divides into 3, and 15 divides into 5, so you can use ratios to find b.
Since 9 divides into 3, we will use this to set up proportions for the missing value:
![\frac{9}{3} = \frac{b}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B3%7D%20%3D%20%20%5Cfrac%7Bb%7D%7B4%7D%20%20)
Cross multiply the fractions.
![3b = 36](https://tex.z-dn.net/?f=3b%20%3D%2036)
Divide both sides by 3.
![b = 12](https://tex.z-dn.net/?f=b%20%3D%2012)
The missing value is
12.
