Answer:
x=-7
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
40 + x+57 + 90 =180
Combine like terms
187 +x = 180
Subtract 187 from each side
187-187 +x = 180-187
x = -7
You need to have variables one one side and constants on the other. ax - ax + by = c - ax
by = c - ax
by/b = (c - ax)/b
y = (c - ax)/b
The answer should be 117.6. tell the teacher that the amount of meters is wrong or the answers are wrong
sorry :(
8.8 *10^3 (2 sig fig)
2.9 *10^3 (2 sig fig)
"commutative property" in addition and multiplication means that you can exchange the places of integers in addition and multiplication and still get the same answer.
For this question:
10 + 8 = 18 can be rewritten using commutative property as: 8 + 10 = 18
