Two angles o a triangle each measure 70 degrees what is the measurement of the third angle in degrees

hjlf

The 3 angles of a triangle, when added, = 180 degrees

so if 2 of them are 70.....70 + 70 = 140
then the 3rd will be 180 - 140 = 40 degrees <==

Can someone help me please? and probably explain it if you can.

Hey there! :)

Answer:

p(x) = 6x - 15

Step-by-step explanation:

If p(x) = r(x) - c(x), subtract the two equations. Therefore:

p(x) = 10x - (4x + 15)

p(x) = 10x - 4x - 15

Combine like terms and simplify:

p(x) = 6x - 15

Find the distance between points P(5, 1) and Q(3, 4) to the nearest tenth

pav-90 [236]

Answer:

$\sqrt{13}$ units

Step-by-step explanation:

The distance formula is $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ where $d$ is the distance between points $(x_1,y_1)$ and $(x_2,y_2)$ . Let $(x_1,y_1)\rightarrow(5,1)$ and $(x_2,y_2)\rightarrow(3,4)$ , thus:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d=\sqrt{(3-5)^2+(4-1)^2}\\\\d=\sqrt{(-2)^2+(3)^2}\\\\d=\sqrt{4+9}\\\\d=\sqrt{13}$

Therefore, the distance between points P(5,1) and Q(3,4) is $\sqrt{13}$ units.
