Answer:
8
Step-by-step explanation:
-3 + 6/n + 9
for n=3 is
-3 + 6/3 + 9
= -3 +2 + 9
= -1 + 9
= 8
Answer:
- 13
Step-by-step explanation:
Given
- 2 + 3(1 - 4) - 2 ← evaluate parenthesis
= - 2 + 3(- 3) - 2 ← perform multiplication
= - 2 - 9 - 2
= - 13
Hi there,
your question is asking for the angle of the central circle, and the formula is: the two arcs' sum divided by 2
So,
(60 + 40) ÷ 2 = 50
The answer is 50°
Hope I helped :p
Answer:
1. m ∠ 1 = 113°
2. m ∠ 2 = 67°
3. m ∠ 4 = 67°,
4. m ∠ 5 = 113°
5. m ∠ 6 = 67°
6. m ∠ 7 = 113°
7. m ∠ 8 = 67°
Step-by-step explanation:
Given AB║CD and m║n and m∠3=113°
Solution, since m and n are parallel lines so AB and CD are transversal lines.
So ∠2 and ∠3 makes a linear pair whose sum is equal to 180°.
(∠2 and ∠8),(∠3 and ∠7),(∠1 and ∠5),(∠4 and ∠6) are alternate interior angles.
(∠2 and ∠4),(∠1 and ∠3),(∠5 and ∠7),(∠6 and ∠8) are corresponding angles.
When two lines are parallel and their is a transversal line then the measure of alternate angles are equal and also the measure of corresponding angles are equal.
![m\angle 2 + m\angle 3 = 180\\m\angle 2 + 113 = 180\\m\angle2=180-113=67\\m\angle2=m\angle8=67 \ (alternate\ interior\ angle)\\m\angle3=m\angle7=113 \ (alternate\ interior\ angle)\\m\angle3=m\angle1=113 \ (corresponding\ angle)\\m\angle2=m\angle4=67 \ (corresponding\ angle)\\m\angle4=m\angle6=67 \ (alternate\ interior\ angle)\\m\angle1=m\angle5=113 \ (alternate\ interior\ angle)](https://tex.z-dn.net/?f=m%5Cangle%202%20%2B%20m%5Cangle%203%20%3D%20180%5C%5Cm%5Cangle%202%20%2B%20113%20%3D%20180%5C%5Cm%5Cangle2%3D180-113%3D67%5C%5Cm%5Cangle2%3Dm%5Cangle8%3D67%20%5C%20%28alternate%5C%20interior%5C%20angle%29%5C%5Cm%5Cangle3%3Dm%5Cangle7%3D113%20%5C%20%28alternate%5C%20interior%5C%20angle%29%5C%5Cm%5Cangle3%3Dm%5Cangle1%3D113%20%5C%20%28corresponding%5C%20angle%29%5C%5Cm%5Cangle2%3Dm%5Cangle4%3D67%20%5C%20%28corresponding%5C%20angle%29%5C%5Cm%5Cangle4%3Dm%5Cangle6%3D67%20%5C%20%28alternate%5C%20interior%5C%20angle%29%5C%5Cm%5Cangle1%3Dm%5Cangle5%3D113%20%5C%20%28alternate%5C%20interior%5C%20angle%29)
Hence the measure of all angles are:
1. m ∠ 1 = 113°
2. m ∠ 2 = 67°
3. m ∠ 4 = 67°,
4. m ∠ 5 = 113°
5. m ∠ 6 = 67°
6. m ∠ 7 = 113°
7. m ∠ 8 = 67°
