The sum of the angles of any triangle is Find all the missing angles in the triangles. Write each answer on the line
provided beside the corresponding letter.

A: 40

B: 90

C: 53.5

D: 34

E: 90

F: 52.9

G: 90

H: 59.6

I: 119.1

J: 30.4

K: 90

L: 72

M: 107.3

N: 47.7

O: 36

P:90

Step-by-step explanation: In every triangle the angles will add up to 180. The little square means 90. You can just subtract all the number you already know in the triangle from 180 to find the one you don’t know.

y = x + 95

y = 42 + 95

y=137 mm hg

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
