Answer:
17/30
Step-by-step explanation:
2/5 + 1/6 = 17/30
Make them easier to add by making them have the same denominator.
2/5 = 12/30
1/6 = 5/30
12/30 + 5/30 = 17/30
Answer:
m∠6 = 90°
Step-by-step explanation:
∠1 and ∠2 are a linear pair. This means they are supplementary, or their measures sum to 180°. To find m∠2, we subtract m∠1 from 180:
180-140 = 40°
The measure of ∠2 is 40°.
The sum of the measures of the angles in a triangle is 180°. We have ∠2 and ∠3; to find the measure of ∠6, we subtract these two from 180:
180-(40+50) = 180-90 = 90°
