Answer:
x = 10 units
Explanation:
First, let's consider the smaller triangle.:
It is a right-angled triangle, therefore, we can use the special trig functions.
tan θ = opposite / adjacent
tan 45 = opposite / 5
opposite = 5
Now, for the larger triangle:
It is also a right angled triangle which means that we can use the special trig functions.
sin θ = opposite / hypotenuse
sin (30) = 5 / x
x = 10 units
Hope this helps :)
EDIT:
Order of operations doesn't matter in addition. So you can add them in any order.
Pretend that 300 is b and 400 is a. In Commutative property in the letter term b+a=a+b. (The value is 700)
Answer: 1 1/3
Step-by-step explanation:
-4 + 5 = 1
-1/3 + 2/3 = 1/3
OR
Turn them both into mixed numbers: -13/3 + 17/3
-13/3 + 17/3 = 4/3 = 1 1/3
