(c) ∠ECF and ∠BCF
Step-by-step explanation:
Complementary angles total 90°. Here, 90° angle BCE is divided by ray CF into two complementary angles. They necessarily have a total of 90°.
∠ECF and ∠BCF
-5x + 3x > 22
-2x > 22
x < 22/-2 (greater than sign changes to less than sign when you divide with negative number)
x < -11
Answer:
Step-by-step explanation:
x + 4 = 2x + 1
-x -x
4 = 1x + 1
-1 -1
3 = 1x
-- --
1 1
3 = x
Check:
3 + 4 = 2(3) + 1
7 = 6 + 1
7 = 7
