Answer:

x = 29

Step-by-step explanation:

Sum of interior angles of a triangle = 180°

⇒ 59 + 3x + x + 5 = 180

⇒ 4x + 64 = 180

⇒ 4x = 116

⇒ x = 29

Answer:

C) 29

Step-by-step explanation:

All triangles add up to 180 degrees,

subtract the known 59 from 180 to get 121.

then combine (3x) and (x + 5) to get 4x + 5

4x + 5 = 121 solve

4x = 116

x = 29

the ratio of the measures of the three angles in a triangle is 2:9:4. find the measures of the angles

givi [52]

Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°
I hope it is helpful:D
