Step-by-step explanation:
the inner top vertex angle seems to be 90°, so x = 90° too. all angles around a single point in one side of a line are in total 180°.
also, remember, all angles inside a triangle always sum up to 180°.
so, the third inner angle of the triangle is
180 - 90 - 40 = 50°.
that makes z = 180 - 50 = 130°
and y = 180 - 40 = 140°.
Answer:
-4
Step-by-step explanation:
8+4y= -8
4y= -8 -8
4y= -16
divide both sides by the coeffient of the variable. in this case divide both sides by 4
y=-4
The transitive property is used. Its the property that if a = b and b = c, then a = c. You can think of it as linking a chain together.
It would be 7.62
you would have to use pythagorean theorem and do 7 squared plus 3 squared. you would get 58. then you have to square root 58 which would give you 7.62
It's a isosceles right angled triangle
