Answer:
x = 60
Step-by-step explanation:
That square on the angle means 90 degrees so since the other angle is 30 that means x has to be 60
The sum of angles of a triangle is 180°.
48 +(6x -28) +2x = 180
8x +20 = 180
8x = 160
x = 20
∠B = (6x -28)° = (6*20 -28)° = 92°
∠C = 2x° = 40°
___
x = 20
∠B = 92°
∠C = 40°
0.4 * x = 68
x = 68/0.4
x = 170
check:
0.4 * 170 = 68
Answer:
D
Step-by-step explanation:
using the rule of exponents
= 
substitute x = - 3 into f(x)
f(- 3) = 4(
= 4 × 
= 4 ×
