The measures of the angles of a triangle are in the ratio 2:4:9 find the measures of all three angles
1 answer:
all angles = 180 degrees total
add the ratios: 2 +4 +9 = 15
180/ 15 = 12
12*2 = 24
12*4 = 48
12*9 = 108
108 + 48 + 24 = 180
the three angles are: 24, 48 and 108

The answer is <a is congruent to < d
because you already have <abe = <dbe
Answer:
y=-2/3x+20/3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-6)/(4-1)
m=-2/3
y-y1=m(x-x1)
y-6=-2/3(x-1)
y=-2/3x+2/3+6
y=-2/3x+2/3+18/3
y=-2/3x+20/3
C the third one
