Answer:
Step-by-step explanation:
Given
Required
The measure of each angle
First, we calculate the length of the three sides of the triangle.
This is calculated using distance formula
For AB
So:
For BC
For AC
So, we have:
By representation
So, we have:
By cosine laws, the angles are calculated using:
Collect like terms
Solve for
Take arc cos of both sides
Collect like terms
Solve for
Take arc cos of both sides
For the third angle, we use:
--- angles in a triangle
Make C the subject
Answer:
The number of each kind of apartment in the building is 130 .
Step-by-step explanation:
Given as :
The total number of floor in a building = 15
The number of apartment on each floor = 26
So, The total number of apartment = 26 × 15 = 390
The number of kinds of apartment in the building is 3 , i.e 1-bedroom , 2-bedroom , 3-bedroom
Let The number of each kind of apartment in building = x
So, According to question
The number of each kind of building =
or, x =
∴ x = 130
Hence The number of each kind of apartment in the building is 130 . Answer
Answer:

pls can i get brainliest it took soo long to figure out
Answer:
Twelve pence made a shilling
I hope this is the ans
They are the same measurements, because:
from 10x + 5, first do vertical angle.
then, alternate interior angle,
then vertical angle again,
and another alternate interior angle.
For each vertical and alternate interior angles, the measurements stay the same.
Set them equal to each other, isolate and solve for x.
10x + 5 = 11x - 1
First, isolate the x. Subtract 10x from both sides, and add 1 to both sides
10x (-10x) + 5 (+1) = 11x (-10x) -1 (+1)
Simplify
5 + 1 = 11x - 10x
6 = x
x = 6
6 is your answer for x.
hope this helps
