Question

What are the degree measures of A and B if C = 54, A = x and B = 2x for triangle ABC?

Answer 1

54+x+2x=180
Can u find nw?

Answer 2

a.15 and 30

b. 18 and 36

c. 21 and 42

d. 25 and 50

Answer 3

angles in a triangle sum up to 180
so u get
x+2x+54=180
can u solve this to get x ??

Answer 4

x+2x+54=180
3x+54=180
3x=180-54=126
x=126/3=42

Answer 5

A=x=42
B=2x=2*42=84

Answer 6

<A + <B + <C = 180

Answer 7

Yes by angle sum property of a triangle ;)

Answer 8

A=X
B=2x

Answer 9

so i have to find that?

Answer 10

Put the value of x that is 42

A=x=42
B=2x=2*42=84

Answer 11

so A=42
B=21??

Answer 12

oh

Answer 13

so 54 + x + 2x = 180
54 + 3x = 180
3x = 180 - 54 = 126
Hence x = 42, 2x = 2(42) = 84
so A =42, B = 84

Answer 14

B=2x= 2*42=84

Answer 15

@Colcaps

Answer 16

but the answer doesent answer my problem the coices are here


15 and 30

18 and 36

21 and 42

25 and 50

Answer 17

wait

Answer 18

21 and 42 is simplified thank you guys

Answer 19

Then its possible that some of the angles are exterior angles

Answer 20

I suppose x and 2x to be exterior

Answer 21

i found the answer its 21 and 42 im not looking for the angle but thanks anyway

Answer 22

Then x + 2x = 54
3x = 54
x = 18, 2x = 2(18) = 36

Answer 23

so
