Step-by-step explanation:
Move all terms that don't contain C to the right side and solve.
Answer:
A
Step-by-step explanation:
using the sine ratio in the right triangle, then
sin 45° =
= 
multiply both sides by 5
note the exact value of sin 45° = 
x = 5 × sin 45° = 5 ×
= 
Answer:
1. B
2. B and C
3.C
4.B the answer is 238 but i guess the rounded
Step-by-step explanation:
4x - 26 = 2x - 4....subtract 2x from both sides
4x - 2x - 26 = -4...add 26 to both sides
4x - 2x = -4 + 26...combine terms
2x = 22...divide both sides by 2
x = 22/2 = 11
OR
4x - 26 = 2x - 4.....subtract 4x from both sides
-26 = 2x - 4x - 4....add 4 to both sides
-26 + 4 = 2x - 4x...combine terms
-22 = -2x....divide both sides by -2
-22/-2 = x
11 = x
