Answer:
x=11
Step-by-step explanation:
13×11+26=117
5×11+8=63
117+63=180
Count the rise and run to find the slope, 1. Next, find the y-intercept-(-1). Now make the slope-intercept equation- y = 1x - 1. Double check, put x = 2 in the equation- y = 1(2) - 1 (=) y = 2 - 1 (=) y = 1.
So, the slope-intercept equation for this line is y = 1x - 1.
Answer:
Angles of triangle are 40°,60° and 80°.
Step-by-step explanation:
Given:
if angles of a triangle are 2 is to 3 is to 4.
Let the common factor between the angles be 'x'.
So we can say that;
Angle 1 = 
Angle 2 = 
Angle 3 = 
We need to find the value of each angle.
Solution:
Now we know that;
"Sum of all angles of triangle is 180°."
framing in equation form we get;

Substituting the values we get;

Dividing both side by 9 we get;

Angle 1 =
.
Angle 2 = 
Angle 3 = 
Hence Angles of triangle are 40°,60° and 80°.
