We know that the sum of the internal angles in each triangle is 180°.

Therefore we have the equation:

$m\angle C+m\angle D+m\angle E=180^o$

substitute and solve:

$79+(6x+11)+(7x-14)=180\\(6x+7x)+(79+11-14)=180\\13x+76=180\ \ \ |-76\\13x=104\ \ \ |:13\\x=8$

We have

$m\angle N=3x+18$

substitute the value of x to the expression:

$m\angle N=3(8)+18=24+18=42$

Answer: m∠N = 42 degrees

Answer:

The answer is D.

Step-by-step explanation:

Well since there are 4 values calculated then 2 would be above the mean because plus the 2 values above the mean. I don't know if it makes since though.

Ab over 2 equal 2a minus 1,express a in terms of b

sasho [114]

$\frac{ab}{2}$ = 2a - 1

2( $\frac{ab}{2}$ ) = 2(2a - 1) multiplied both sides by 2

ab = 4a - 2 distributed the 2 on the right side

ab - 4a = -2 subtracted 4a from both sides

a(b - 4) = -2 factored out "a" from the left side

a = $\frac{-2}{b - 4}$ divided (b - 4) on both sides

Answer: a = $\frac{-2}{b - 4}$

Explain the distance formula. Then use it to calculate the

Alex777 [14]

Answer:

$dAB=10\ units$

Step-by-step explanation:

we know that

The distance formula is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse. The hypotenuse of the triangle is the distance between the two points

The formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$
