Answer 1

Answer:

The angles are 60°,48°,72°

Step-by-step explanation:

leave the angle be 2x and 3x

60°+2x+3x=180°

5x=180°-60°= 120°

x=120/5=24

2x=2*24=48

3x=3*24=72

The angles are 60°,48°,72°

Answer 2

$\huge\red{correct}$$\huge\red{question}$

If one angle of a triangle is 60° and the other two angles are in the ratio 2 :3, find the two angles .

$\huge\underline{\underline{\bold{\red{A}\green{n}\orange{s}\pink{w}\blue{e}{r}}}}$

48°, 72°

Step-by-step explanation:

$\sf\large\underline\purple{Given:)}$

• the first angle

$\sf\large\underline\purple{to}$$\sf\large\underline\purple{find :)}$

• we have to find two Angles

$\sf\large\underline\purple{Let's}$$\sf\large\underline\purple{start:)}$

• we know that sum of three angles is equal to 180

one angle of triangle = 60

60 + x + x = 180

the ratio between second and third angle = 2:3

60 + 2x+ 3x = 180

2x + 3 x = 180 - 60

2 x + 3x = 120

5x = 120

$x = \frac{120}{5}$

x = 24

so, the second angle = 2× 24 = 48 °

the third angle = 3× 24 = 72 °

angles are 60° , 48° ,72°

let verify it :

• we know that sum of all three angles = 180
• 60° + 48° + 72° = 180°
• we have done verify also!

Hence , we have done !
