Answer:
Step-by-step explanation:
The sides of a 45°-45°-90° triangle are in the ratio 1:1:√2
The side opposite the 90° angle is 12√2.
a = c = (12√2)/√2 = 12
The sides of a 30°-60°-90° are in the ratio 1:√3:2.
The length of the side opposite the 30° angle is 12 units.
d = length of side opposite 60° angle = 12√3 units
b = length of side opposite the 90° angle = 2×12 = 24 units
Sin P = opp/hyp
sin P = 15/17
P = sin⁻¹(15/17)
P = 61.93° (nearest hundredth)
Answer:
arithmetic
Step-by-step explanation:
It is arithmetic because the terms go up by 15 . That is the common difference is 15.
