D. X=3cm
Since the triangles are similar, just set up a proportion to solve for x.
4/8=x/6. Then just cross multiply and solve from there.
Answer: C) 65 degrees
Step-by-step explanation: the next highest is 90, but that would have the arrows in the shape of an L, since its closer than that, its lower than 90, so its 65.
Answer:
Step-by-step explanation:
B + 2C
= w + 10 + 2(-w - 1)
= w + 10 -2w - 2
= -w + 8
<span>you can solve all quadratic equations using this method:
---
x^2 + 4x + 4 = 0
---
the above quadratic equation is in standard form, with a=1, b=4, and c=4

the above quadratic equation is in standard form, with a=1, b=1, and c=0</span>
The answer is A. After you square root both sides, you have to add 3 to both sides and then divide both sides by 4.
