Answer: 10 + 5x
Step-by-step explanation: the base is x. One side is 6 + 3x. The last side is 4 + x. Now add them together 6 + 3x + 4 + x + x. Then simplify to 10 + 5x.
Answer:
<A = 30
<B = 150
Step-by-step explanation:
- cos<A = AK / AB
- AK = 4
- AB = 8
- Cos<A = 4/8
- Cos<A = 1/2
- A = Cos-1(0.5)
- A = 30 degrees
- Since BC and and AD are parallel, the interior angles of <A and <B sre supplementary.
- <A + <B = 180
- 30 + <B = 180
- <B = 180 - 30
- <B = 150
Answer:
1/18 I believe or it should be 1/3. May be wrong, sorry
Answer:15
