In an equilateral triangle (all sides and anges are equal)
angles are 60 degrees each
Answer:
C
Step-by-step explanation:
Parallel and opposite sides of a parallelogram are equal. Hence, we can say:
x + 30 = 2x - 10
and
2y-10 = y +10
Solving first one, we get:
x + 30 = 2x - 10
30+10 = x
x = 40
Also
2y - 10 = y + 10
y = 10 + 10
y = 20
Now, z = x - y, so
z = 40 - 20 = 20
Answer C is right.
Step 2: commutative property of multiplication
Step 3: multiplicative inverse
Step 4: multiplicative identity
The answer to your question is 89
The answer is 3930.
All you have to do is multiply 131,000 * 3 and then divide that by 100.
Hope that helps!
