Answer:

Step-by-step explanation:

(7x - 1) + 79° = 21x + 8

• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.

$(7x - 1) +79 = 21x + 8 \\ 7x - 1 + 79 = 21x + 8 \\ 7x + 78 = 21x + 8 \\ 78 - 8 = 21x - 7x \\ 70 = 14x \\ \frac{70}{14} = x \\ 5 = x \\$

NRS = 21x + 8

$21x + 8 \\ 21(5) + 8 \\ 105 + 8 \\ {113}^{o}$

Can anyone help? thanks in advance!

Kipish [7]

Answer:

B(2,4)

Step-by-step explanation:

A(-1,-9)

M(0.5,-2.5)

with M we can find x₂ and y₂

x = 0.5

x = x₁+x₂/2

0.5 = (-1 + x₂)/2

(x₂ -1)/2 = 0.5

x₂-1=0.5×2

x₂-1=1

x₂=2

for y₂

y= -2.5

y=(y₁+y₂)/2

y=(-9+y₂)/2

-2.5=(-9+y₂)/2

-9+y₂=-2.5×2

-9+y₂=-5

y₂=-5+9

y₂=4

.: coordinates are B(2,4).

Which expression can be used to determine the length of segment AB? On a coordinate plane, triangle A B C has points (4, 3), (ne

JulijaS [17]

Answer:

StartRoot 2 squared + 6 squared EndRoot

Step-by-step explanation:

we have

A(4,3) and B(-2,1)

we know that

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

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

substitute the given values

$AB=\sqrt{(1-3)^{2}+(-2-4)^{2}}$

$AB=\sqrt{(-2)^{2}+(-6)^{2}}$

$AB=\sqrt{40}\ units$

therefore

StartRoot 2 squared + 6 squared EndRoot
