Answer:

35°

Step-by-step explanation:

Angle BPE = 180 - 125 = 55° (supplementary angles)

Angle CPB = CPE - BPE

= 90 - 55 (complementary angles)

= 35°

Answer:

x = 35

Step-by-step explanation:

DPB is a straight line, thus

∠ DPE + ∠ EPB = 180° ← ∠ DPE = 125°, thus

125° + ∠ EPB = 180° ( subtract 125 from both sides )

∠ EPB = 55°

∠ CPE is aright angle = 90°, thus

x = ∠ CPE - ∠ EPB = 90° - 55° = 35°

Find the value of x so that m||n
jasenka [17]

Answer:x=17

Step-by-step explanation:

Set 6x+5+5x-12 equal to 180

Simplify into 11x-7=180

Add 7 to both sides to get 11x=187

Divide both sides by 11 to get x=17

Find the distance between M(-2,3) and N(8,2)
AnnZ [28]

Answer:

d=\sqrt{101}

Step-by-step explanation:

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

d=\sqrt{(8-(-2))^2+(2-3)^2}

d=\sqrt{(8+2)^2+(-1)^2}

d=\sqrt{(10)^2+1}

d=\sqrt{100+1}

d=\sqrt{101}

The low temperatures in Anchorage, Alaska, for a week were − 6, − 3, − 1, 1, − 3, − 9, and − 14 degrees Celsius. What two temper
Inessa05 [86]

The two temperatures could be removed so that the average of the remaining numbers is the same as the average of the original set of numbers are -1 and -9

Step-by-step explanation:

The formula of the average of a set of data is A=\frac{S}{N} , where

  • S is the sum of the data in the set
  • N is the number of the data in the set

∵ The low temperatures in Anchorage, Alaska, for a week were

   − 6, − 3, − 1, 1, − 3, − 9, and − 14 degrees Celsius

∴ The set of the data is { -6 , -3 , -1 , 1 , -3 , -9 , -14}

- Add the data in the set

∵ S = -6 + -3 + -1 + 1 + -3 + -9 + -14

∴ S = -35

∵ The set has 7 data

∴ N = 7

- Use the formula of the average above to find it

∴ A=\frac{-35}{7}

∴ A = -5

∴ The average of the original set of numbers is -5

To keep the average the same after removing two numbers multiply the average by the new number of data to find the new sum

∵ The number of data after removing two numbers is 5

∴ N = 5

∵ A = -5

- By using the rule of average

∴ -5=\frac{S}{5}

- Multiply both sides by 5

∴ -25 = S

∴ The new sum is -25

- Lets find which two numbers of have a sum of -10 because

   the difference between -35 and -25 is -10

∵ -1 + -9 = -10

∵ -6 + -3 + 1 + -3 + -14 = -25

∴ We could removed -1 and -9

The two temperatures could be removed so that the average of the remaining numbers is the same as the average of the original set of numbers are -1 and -9
