Answer:
∠AOB and ∠COD are vertical angles
∠DOE and ∠COD are complementary, adjacent
∠AOB and ∠AOD are supplementary, adjacent.
Step-by-step explanation:
Let's start with ∠AOB and ∠COD.
Looking at this, we can see they are the same angles formed by two lines that intersected. These are vertical angles as they are opposite each other.
∠DOE and ∠COD together form the angle ∠EOC, which is a right angle. Complementary angles are any of two that add up to 90°, so these two angles are complementary. They are also adjacent because they are right next to each other.
∠AOB and ∠AOD together form the angle ∠BOD, which has a measure of 180°. Supplementary angles are any of two that add up to 180°, so ∠AOB and ∠AOD are supplementary. They are also adjacent as they are touching/right next to each other.
I hope this helped!
Answer:
a slope of 3 is steeper
Step-by-step explanation:
assume if we run by 1 rising by 2 is less than 3. Which in terms of math 3/1 is much steeper than 2/1.
or 3 skipped steps on a staircase is more steeper incline than 2 skipped steps.
Answer:
L = 55 in, W = 20 in
Step-by-step explanation:
Hi there!
First we have to set up an equation for the length, which can be written as 3x - 5.
The formula for perimeter of a rectangle is 2l + 2w = p, so we can plug in some values here.
l = 3x - 5
w = x
Now we just have to solve!
When we combine like terms and add ten to both sides, we are left with
, which means x = 20
Using this, that means the width is 20
We can find the perimeter by plugging 20 in for x.
This means the length is 55.
I need the full equation to solve this, but the best I can do is tell you to combine like terms for 4(x + 63) you get 4(64x), Part B is 2,
Answer:
5x-26
Step-by-step explanation:
3(3x-6)-4(x+2)
Distribute the 3 and -4.
9x-18-4x-8
Combine like terms.
5x-26
