Answer:
True
Step-by-step explanation:
56 has two digits. You cannot takeout either of those two numbers out so they are both significant, hence significant digits.
Answer:
see explanation
Step-by-step explanation:
x = 65° ( vertically opposite angles )
y = 71° ( alternate angles )
The sum of the 3 angles in a triangle = 180° , then
x + y + z = 180° , that is
65° + 71° + z = 180°
136° + z = 180° ( subtract 136° from both sides )
z = 44°
So x = 65°, y = 71° , z = 44°
