In order to solve this problem, you must create a ratio. If Bangor is 240 miles away and Javier has only 4 hours to get there, we can divide 240 by 4 which equals 60 miles per hour.
Answer:
122°
Step-by-step explanation:
The measure of the central angle is twice the measure of the inscribed angle that subtends the same arc.
∠ABC = 2×∠ADC = 2×61°
∠ABC = 122°
1/6* (15a+20b)
= 1/6* 15a + 1/6* 20b (Distributive property)
= 2.5a + 10/3*b
The final answer is 2.5a+ 10/3b
Hope this helps~
