Answer:
x = 20 degrees and y = 70 degrees
Step-by-step explanation:
The first thing you do is work out the angle next to 180 degrees
180 - 40 = 140
Bottom angles in an isosceles triangle are equal.
180 - 140 = 40
40/2 = 20
so x = 20 degrees
The next thing is right angle - 20 = 70 degrees
Angles in a triangle add up to 180 degrees
70 + 40 = 110
180 - 110 = 70
so y = 70 degrees
The answer is C. This is because when you covert the fraction into a decimal, you get 2.33333(etc) and the decimal doesn’t end.
The answer is x < 12
1) Minus 6 from both sides of the inequality
2) Multiply both sizes by 4
3) Divide both sides by -3
4) Swap the direction of the inequality (You always do this when you multiply/divide both sizes of an inequality)
5) You should have x < 12
