Which sets of values can be the measures of the exterior angles of a triangle? 120°, 110°, 130° 35°, 103°, 122° 123°, 87°, 220°

kodGreya [7K]

Answer:

The values are :

we khow that the sum of a triangle angles is 180°
the sum of each set exterior and interior angle is 360°
so 360+360+360-180 = 900 is the sum of exterior angles of a triangle
we can see no set can satisfy this condition

The volume of prism A is 60 cubic units, and the volume of prism B is half the volume of prism A. What is the value of a?

Alexxx [7]

Answer:

a=3.91

Step-by-step explanation:

V=a^3

since volume of B is Half of A then : V of A = 2 volume of B

a^3=2a^3

a^3 for A=60

or ∛a = ∛60= 3.91

volume of B =1/2 A =30
