The triangle BAC has two known measurements 30 and 90 so add those together and subtract by 180
30 + 90 = 120
180 - 120 = 60°
It’s B because you just rotate the triangle not the angles. Look at a regular and the opposite of the way it’s going is counterclockwise.
Step-by-step explanation:
given that
first term (a1) = 100

common ratio = 1/ 2
the series in Geometric Progression
the first five terms are
a1 = 100
a2 = 100/2 = 50
a3 = 50/ 2 = 25
a4 = 25/ 2 = 12.5
a5 = 6.25
Answer:
4 gold 8 silver 6 bronze
Step-by-step explanation:
because ratio is 2:4:3 total is 9 in ratio I just double that to get 18
so 4 gold 8 silver 6 bronze
Answer:
The answer is:
a) 2/10= 1/5 or 0.2
b) 9/24= 3/8 or 0.375
