Don’t think this is reliable anyone can type stuff down so I wouldn’t recommend it
The angles are 45° 60° and 75°
Elaboration：
Let the three angles be 3x 4x and 5x
( since the sum of interior angles of triangle=180° )
3x+4x+5x= 180
12x = 180
x = 15
3x= 45
4x= 60
5x= 75
X=9
You add 3 to both sides which leaves you with 2x=18 and then divide by two and that gives you x=9
Answer:
Therefore the required resulting equation is
6 x minus 15 y = negative 63.
Negative 15 x + 15 y = 90
Step-by-step explanation:
Given:
......................Equation ( 1 )
......................Equation ( 2 )
To Find:
Expression after multiplying to eliminate y term,
Solution:
So to eliminate 'y' term we need to multiply equation 1 by a constant 3 and equation 2 by a constant -5, such that equations becomes
.....( 1 )
.....( 2 )
so now by adding new equation one and two we can eliminate y term that means -15y and +15y will get cancel,
Therefore the required resulting equation is
6 x minus 15 y = negative 63.
Negative 15 x + 15 y = 90
First you want to get it into standard form. which would mean you get the x of the side of the y and divide everything by the y's coefficient in this case 3.
3y-x=a
3y=x+a
y=1/3x+a
Now your going to want to turn this into a perpendicular li e which means you flip the coefficient and make it negitive
y=-3x+a
then we fill in the points.
-1=-3(2)+a
Solve
-1=-6+a
-1+6=a
5=a
Now put it in standard form.
y=-3x+5
