Step-by-step explanation:
sum of all the angles in a triangle=180
let the angles be 2x, 4x and 3x
so, 2x+4x+3x=180
9x=180
x=20
so smallest angle 2x= 2(20)= 40 degrees
Triangle angles add up to a total of 180 degrees.
X will substitute for the second angle.
(X - 10) will substitute for the first angle, which is 10 less than the second angle (x).
The third angle is a right angle which is 90 degrees.
The equation therefore, the summation of the angles:
90 + x + (x - 10) = 180
Join like terms:
80 + 2x = 180
Solve for x:
2x = 100
x = 50
This means that:
The second angle is 50.
The first angle is 50 - 10 which is 40.
We can double check by adding the angles 50, 40, and 90 together to get 180.
Just add a 0 to the end of all of em♀️
Answer:
Well we are adding by 10 for every 1 increase in x. So slope is 10 / 1 = 10. (1. a slope of 10) is an answer.
We want x = 1 to have y = -5 Slope form is y=mx+b. We know m = 10 bec slope is 10. We have the point (1,-5) on the graph so we solve for b by plugging:
-5 = 10(1) + b and this is b = -15. So graph has function y = 10x-15.
b is the y-intercept so (3. a y-intercept at (0,−15)) is an answer.
