The ratio of the measure of the three angles of a triangle is 3:4:8. Find the mesure of the large angle

96°

Step-by-step explanation:

Ratio of angles :

3 : 4 : 8

Sum of angles in a triangle = 180°

The value of the largest angle = angle with the largest ratio

This is the value of the angle with ratio 8

Sum of ratio : (3 + 4 + 8) = 15

Hence,

(8 / 15) * 180°

(8 * 180°) / 15

1440 / 15

= 96°

no, because the sides are not congruent

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
