Answer:
let the number be x, so that the two numbers are x and x - 32 The first number is x = 62.
The second number is x - 32 = 62 - 32 = 30.
Step-by-step explanation:
x + x - 32 = 92
or, 2x = 92 + 32
or, 2x = 124
or, x = 124/2 = 62
Answer: 121
<u>Multiply</u>
20%×605=121
Note: When finding the percent of a number multiply the percent times the number.
Answer:
55°
Step-by-step explanation:
Angles x and 125° are linear pair,
So,
x + 125° = 180°
x = ( 180 - 125 )°
x = 55°
Answer:
P=40
Step-by-step explanation:
find the distance between each vertices:
between the following points to find the length of each sides, octagon has 8 sides , since it is regular pentagon the distance between each vertices =5
the length of each side of octagon=5
to check :d=√(x2-x1)²+(y2-y1)²
(-2,-4) and (1,0) , d=√[(1-(-2)]²+(0+4)² =√3²+4², d=5
(1,0) and (1,5) , d= 5
(1,5) and (-2,9) , d=5
(-2,9) and (-7,9) , d=5
(-7,9) and (-10,5) , d=5
(-10,5) and(-10,0) , d=5
(-10,0) and(-7,-4), d= 5
(-7,-4) and (-2,-4), d=5
perimeter of octagon = 8a ( a is the length of the side)
p=8(5)
P=40
