And a mechanism is steering mechanism in cars or the winding mechanism of a watch.
Step-by-step explanation:
Even integer: 2 x a, where a is a natural number without 0;
Odd integer : 2 x b + 1 , where b is a natural number;
So, 2 x a + 2 x b+ 1 = 2 x ( a + b ) + 1, which is an odd integer.
From angle bisector theorem, we know that:
Moreover:
so:
and
Answer:
-7
Step-by-step explanation:
y=3x-7
x=0 ⇒ y= 3*0-7= -7
Angle 1 is a right angle =90 °
so 5x-85=90
5x=90+85
5x=175
x=35
