Tan(A) = a/b
a = b*tan(A) = 10.58*tan(36.15°) = 7.729 . . . yd
The answer is the Associative Property of addition.
Associative property of real numbers is related to how we use the parenthesis in the expression while adding or multiplying, we always get the same answer.
like a + b + c = (a + b) + c = a + (b + c)
The given equation is 4.5 + 9.8 +1.5 + 3.2 = (4.5 + 9.8) + (1.5 + 3.2) = (4.5 + 1.5) + (9.8 + 3.2)
72.5+32.7= 105.2
Triangle angles have to equal 180
180-105.2= 74.8
Third angle= 74.8 degrees
Length of the aquarium is 35 yd
Step-by-step explanation:
- Step 1: Volume of the aquarium = 210 yd³ given by Volume = length × width × height. Width = 3 yd and Height = 2 yd
Length = Volume/Width × Height
= 210/3 × 2 = 210/6
= 35 yd
Answer:
See Below
Step-by-step explanation:
x(2x) - 4(2x) + x(3) - 4(3)
= 2x² - 8x + 3x -12
= 2x²-5x-12
