Answer:
Step-by-step explanation:
Let's write a system of equations. I'm going to call them w, x, y, and z.
w = 4x (because m∠1 is 4 times m∠2)
w + x = 90 (bc ∠1 and ∠2 are complementary, meaning they add up to 90)
w = y (bc ∠1 and ∠3 are vertical angles, meaning they are equal)
y + z = 180 (bc ∠3 and ∠4 are supplementary, meaning they add up to 180)
When we substitute w=4x into the second equation, we get 5x=90 → m∠2 = 18°. Since w=4x, m∠1 = 18*4 = 72°. Since w=y, m∠3 = 18°. Finally, because y+z=180, m∠4 = 180-18 = 162°. Hope this helps!
Answer:
y+9=-1(x-4)
Step-by-step explanation:
Point Slope Form is:
When:
'm' is the slope.
is the coordinate.
We are given the slope of -1 and the coordinate of (4,-9).
So:
Using the information and replacing the values we get:
So, the line equation in point slope form should be: y+9=-1(x-4)

Answer:
B. 600 ft
Step-by-step explanation:
The formula for the Perimeter of a right triangle = Side a + Side b + Side c
The perimeter of a right triangle is 60 feet
If the lengths of the sides of the triangle are each multiplied by 10, what is the perimeter of the new right triangle?
Hence, the perimeter of the new right triangle = 10 × 60ft
= 600ft
Option B is the correct Option.
