Answer:
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
40° is the smallest angle of the triangle.
Hope it helps!
a=15
Solve for a by simplifying both sides of the equation, then isolating the variable.
30,6
(b, a)
Example if D was (3, 2) and reflects across y = x, D' will be (2, 3)
