Where’s the angle? Is there a picture of it?
The answer is 0000000.474565743727264647.
It is given that the measurement of arc AC = 155 . And AB is the diameter, so measurement of arc AB=180 degree . Therefore arc BC = arc AB - arc AC = 180-155=25 . And the radius divides chord CD in two equal parts, so it divides the arc too in two equal parts. Therefore if the measurement of arc CB =25 , then the measurement of arc BD =25 too. Hence x =25 .
Answer:
Yes, you can use similar triangles to find x
Answer:
a=-27
Step-by-step explanation:
⅓a-6=-15
multiply by 3 on both sides
3(⅓a-6)=3(-15)
a-18=-45
add 18 on both sides
a=-45+18
a=-27
