A triangle interior angles add up to 180
so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees
Angle B= 45 degrees
Angle A = 45 degrees
A and B are congruent since they are alternate exterior angles
5x-15 = 2x +21
5x = 2x +36
3x=36
X=12
B)
2x12+21 = 45
A)
5x12-15 =45
Answer:
x = 34
Step-by-step explanation:
The angles are corresponding angles and corresponding angles are equal if the lines parallel
2x+3 = 71
Subtract 3 from each side
2x+3-3 = 71-3
2x = 68
Divide by 2
2x/2 = 68/2
x = 34
The answer would be 13.546
you would do 162.56 divided by 12.
Answer:
(C) 1/3
Step-by-step explanation:
The slope intercept form: y = mx + b.
Note:
m = slope
b = y-intercept
x & y = (x , y) for the points.
You are trying to get the y-intercept of the following function given:
f(x) or y = (-2/9)x + (1/3)
1/3 is your answer, or (C), for 1/3 replaces the <em>b</em> inside the equation.
If you really need the slope, the slope of the following equation is (-2/9), which replaces the <em>m</em> inside the equation.
