Question

find the unknown angle in this figure. given x + y=90
please please please solve fast it's argent please please please....​

Answer 1

Answer:

x = 35 ; y = 55 ; z = 125

Step-by-step explanation:

The sum of inner angles of a triangle are equal to 180 degrees

So, 30 + 70 + (x +45) = 180

145 + x =180

x = 180 - 145 = 35 degrees

Given, x + y = 90

35 + y = 90

y = 90 - 35 = 55 degrees

y and z are angles on a straight line whose sum is always 180

y + z = 180

55 + z = 180

z = 180 - 55 = 125 degrees

Answer 2

Answer:

y=65. x=25 z=115

Step-by-step explanation:

in triangle

y+45+70=180(angle sum property)

so y=65

as x+y=90

x=25 (y=65)

z=45+70(exterior Angle property)

z=115plese mark it as brainliest and
