Question 14 of 25 During winter, sea lions on the California coast form large, tightly packed
groups. These groups help the sea lions stay warm. How is thermal energy
being transferred among the sea lions in these groups?
A. Through convection
B. Through radiation
O C. Through insolation
D. Through conduction
SUBMIT

It's D

Explanation:

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11
