Answer:
The length of AC is 222 units.
Step-by-step explanation:
Given AC and AE are common external tangents of G and D.
BC= 123 , GB=20 and AG=101.
We have to find the measure of AC.
As, a straight line joined from the center i.e radius is perpendicular to tangent drawn. Therefore,
In ΔABG, by Pythagoras theorem
⇒ 
⇒ 
⇒ AB=99 units.
Hence, AC=AB+BC=99+123=222 units.
The length of AC is 222 units.
By asking students to answer un-biased, and with detail. Comparing and contrasting each others' genre preference is also useful.
Answer:
It's 2.5
Step-by-step explanation:
12/5=2.4
2.4 x 25/24(1.041...) = 2.5
Answer:
2z+6
Step-by-step explanation:
z+z+6
Combine like terms
2z+6
90 degrees. Looking at a clock, 12 o'clock going all the way around and back is a 360 degree spin. So 12, 3, 6, and 9 are all 1/4 of a 360 degree spin. If you divide 360 by, you would get a 90 degree turn for each of those numbers mentioned above.
