Answer:
<A = 115
<C = 50
Step-by-step explanation:
<A + <B + <C = 180
SO
(4X -13) +15 +(X+18) =180
5X +20 =180
5X = 160
X= 32
LOG IN TO <A = 4*32 -13 = 115
<C = 32+18 = 50
Answer: 4/3
In dividing by fractions, you flip the latter one over. 2/3 * 2=4/3.
Answer:
C. the order in which you add the numbers doesn't affect the sum.
Step-by-step explanation:
The Commutative Property for sum states that the order in which we add the numbers doesn't affect the sum of numbers. i.e.
(a + b) + c = a + (b + c)
Example, (5 + 4) + 2 = 9 + 2 = 11
5 + (4 + 2) = 5 + 6 = 11
Hence, Option C is only correct answer.
Answer:
7.75 ft.
Step-by-step explanation:
a^2 + b^2 = c^2
2^2 + b^2 = 8^2
4 + b^2 = 64
64 - 4 = b^2
60 = b^2
b = 7.75
A x b = -224
a + b = -52
factors of 224
4 and 56
a = 4
b = -56
