Subtract 1.400 from 64.521 and you get 63.121.
Answer: Number 1 is c=89 ft
Number 2 is b=3 cm
Step-by-step explanation: a²+b²=c²
For number 1, 39 ft is a and 80 ft is b so
39²+80²=c² so 39² is 39x39=1521 and 80² is 80x80=6400 so 6400+1521=7921
7921=c² and the square root of 7921 is 89 so c=89 ft
For number 2, a=1.6 cm and c=3.4 cm so 3.4²-1.6²=b²
3.4² so 3.4x3.4 which is 11.56
1.6² so 1.6x1.6 which is 2.56
11.56-2.56=c² and 11.56-2.56=9
Square root of 9 is 3 so b=3
So number 2 answer is b=3 cm

Answer:
2000
Step-by-step explanation:
Expanded form:
80 × (20 + 5)
Partial products:
80 × 20 = 1600
80 × 5 = 400
Sum of partial products: 1600 + 400 = 2000.
Answer:
50 each base angle
Base Angle_1 + Base Angle_2 + Vertex = 180
50 + 50 + 80 = 180
180 = 180
Step-by-step explanation:
Sum of interior angles of Triangle is 18- degrees.
2b + vertex = 180
2b + 80 = 180
2b + 80 -80 = 180 - 80
2b = 100
b = 50
