The measures of the angles of a triangle are in the ratio 6: 3: 7. determine the measure, in
degrees, of the largest, and smallest angle of the triangle.

Step-by-step explanation:

If the ratio of triangle = 6:3:7

Total ratio = 6+3+7 = 16

The sum of angle in a triangle is 180°

1st angle= 6/16 × 180 = 6 × 11.25

= 67.5°

2nd angle= 3/16 × 180 = 3 × 11.25

= 33.75°

3rd angle= 7/16 × 180 = 7 × 11.25

= 78.75°

Largest is 78.75° and smallest is 33.75°

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
