In geometry, you will learn that supplementary angles add up to 180 degrees. Therefore, if two angles have exterior rays that li

e on a line, those two angles are supplementary and they add up to 180 degrees. Supplementary angles are shown below:
You can use this information to set up an equation to solve the problem below for x.

Angle 1 has measure "x". Angle 2 has measure "2x + 30". Find x.

Hint: use the fact that these two angles lie on a line and are therefore supplementary to write the equation:

x + 2x + 30 = 180

Then solve for x.

Estimate the circumference of a circle that has a diameter of 6 ft.
irga5000 [103]
The formula for circumference is C = 2πr, where r is the radius of the circle. However, the radius is half the diameter, so the circumference could also be calculated using the formula C = πd, where d is the diameter of the circle. π is commonly shortened to 3.14.

If the diameter of the circle is 6 feet, an estimate of the circle's circumference is 6 times 3 feet or 18 feet.

Answer:
18 ft

Pam and her sister have a pattern of saving money. Pam saved 40 dollars and her brother saved 100 dollars.
Keith_Richards [23]

Answer:

true

Step-by-step explanation:

Pam saved 40

her bro saves 100

let us take this as ration 40 is to 100 which can also be written in fractional for like 40/100 now we simplify it how by dividing both by 20 so (40/20)/(100/20) which will give 2/5 which can be written as 2 is to 5 so this is true
