Answer:
A. 103 degrees
B. 77 degrees
C. 60 Degrees
Step-by-step explanation:
A. Triangles' interior angles add up to 180, so if you already have 2 angles you just need to put them together, and subtract them from 180.
47+30=77
180-77=103
B. Lines also are 180, so 103-180=77
C. Interior angles of a triangle add up to 180, so 180/3 is how you get your answer.
7/10 = 0.70(7 divided by 10)
3/5 = 0.60(3 divided by 5)
9/11 = 0.81(9 divided by 11)
1/2 = 0.50 (1 divided by 2)
Answer: 9/11
Answer:
you couldve put it here -.-
Step-by-step explanation:
Answer:
Combined equation is 
Step-by-step explanation:
a varies directly as b and inversely as c.
This can be written as
a =
a = kb
where k is the proportionality constant
-------------------------------------(1)
Now lets find the k value bu substituting the given a, b,c values
36 = 12 k
k = 3
Thus the eq(1) becomes
Let us now find the value of a when b=7 and c = 3
a = 7
The answer is 1,280 square feet
You find the area by multiplying the length (40 ft.) by the height (32 ft.)
