Find a, b, and c.

C

Step-by-step explanation:

The base angles are congruent, both 60°, thus the triangle is isosceles and x is a perpendicular bisector ( divides the base into 6 and 6 )

Using the tangent ratio in the right triangle on the left and exact value

tan60° = , then

tan60° = = ( multiply both sides by 6 )

6 × tan60° = x , that is

x = 6

Using the cosine ratio in the same right triangle and exact value

cos60 = , then

cos60° = = ( multiply both sides by y )

y × cos60° = 6 , that is

y × = 6 ( multiply both sides by 2 )

y = 12

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
