Question

the angles of a triangle are in the ratio of 3:7:8. What is the measure of largest angle​

Answer 1

Answer:

80 degree

Step-by-step explanation:

3x+7x+8x=180

therefore x=180/18 =10

8x=80 degree

Answer 2

$\huge{\sf{\underline{\underline{AnSwEr:-}}}}$

Given:-

Ratio of angles of triangle 3:7:8

To find :-

Largest angle

Solution :-

↪️let the first angle be 3x°

↪️let the second angle be 7x°

↪️let the third angle be 8x°

$\boxed{\small \mathfrak{ \red{ \bold { Angle \: Sum \: property \: Of \: triangle = 180°}}}}$

Now,

$\to\ 3x° + 7x° + 8x° =180°$

$\to\ 18x° =180°$

$\to\ x =\frac{180°}{18°}= 10°$

Now put the value of x in our assumption ;

• First angle = 3x° = 3 $\times$10°= 30°

• Second angle =7x° = 7 $\times$ =10° = 70°

•Third angle = 8x° = 8 $\times$ 10°= 80°

$\boxed{\small\mathfrak{ \red { \bold { Largest \: angle = 80° }}}}$
