x=55°, y=35°, z=145°

Step-by-step explanation:

y is vertically opposite to 35, meaning they share the same value.

We can see that x and y add to 90, as together they take up the space as the angle with the box (a symbol for 90°). This means x+y=90, and x=90-y, which can be written as x=90-35 when subbing y with its known value. This solves to x=55.

z and 35 together form a straight line, meaning z+35=180, or z=180-35. This can be solved to z=145.

(x,y,z) = (55,35,145)

Step-by-step explanation:

the angle of a straight line is 180 degrees. We can see that we have a right angle (90 degrees) and 35 degrees. So x must be 180-35-90=55

since the line on the the left if perpandicular with the line going up x and y must add to form a right angle (90 degrees). therefore y = 90-x=35.

finally, z is in a similar situation to x where the angle of the line is 180. We know y so z = 180-y =145

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
