Answer:
∠1 = 23°
Step-by-step explanation:
∠WXZ = ∠WXY + ∠YXZ
Note that ∠2 = 4∠1 ( angle 2 is 4 times angle 1 )
Hence
4∠1 + ∠1 = 115
5∠1 = 115 ( divide both sides by 5 )
∠1 = 23°
Let's say the first day he studied for x minutes.
Each day he studies 5 more minutes than his previous day.
Day 2: x +5
Day 3: x + 10
Day 4: x + 15
Day 5: x + 20
And finally the last day: x + 25
To find the difference all u need to do is take the amount he studied on the first day and subtract it by how much he studied the last day.
X - X + 25
Which gives u a difference of 25
Answer:
40cm and
80cm
Step-by-step explanation:
Given
Sides = 10cm
Perimeter of the first square = 4a
= 4 x 10 = 40cm
For the second square, the sides are increased by 2 times
So 2 x 10 = 20cm
Therefore,
Perimeter = 4 x 20 = 80cm
The perimeter of the second square is twice that of the first square
Answer:
see explanation
Step-by-step explanation:
The division can be expressed as
÷ x³
Change division to multiplication and invert the divisor, that is
×
Cancelling x and x³ by x gives
