First of all why is there 2 similar equation connected to one another?
Second in order to solve this all you need to do is plug in the number and solve for x
For 485
85x+60=485
85x=420
X=5
Do the same thing and you get 3
If angle BCD measures 70° then so does angle DBC (because you have formed an isoceles triangle inside the larger ΔABC and the two legs are equal so the two angles have to be equal. So we have a two 70° angles which leaves 40° for the 3rd angle, which is ∠BDC.
Since ∠BDC and ∠ADB are supplementary (180°) - that leaves 140° for ∠ADB and is our answer
Answer: 47 meters
Step-by-step explanation:
The equation for the diameter of a circle is 
, so we just multiply the diameter (15) by 
. 
, or roughly 47.1238898038. Rounded to the nearest meter, 47 meters. Also, happy pi day!
Answer:
55
Step-by-step explanation:
CE is a bisector so DE has the same measure as BE.
It can be written as √64·√x¹⁶ = 8x⁸, so answer B.
