Answer: b = 90
Step-by-step explanation:
Full triangle is 180
5 + 4 = 9 + 1 (the smallest angle)
180 ÷ 10 = 18
First and smallest angle is 18
p= 18
Second angle is 72
18 × 4 = 72
Thrid angle is 90
18 × 5 = 90
b = 90
18 + 72 = 90 + 90 = 180
Answer:
-4, 55
1/2 pounds
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2)
the train's average rate of speed would be 57.8 mph
Divide 1445 with 25 and then you get your answer
