Answer:
a.
Step-by-step explanation:
you add 2 & 3 ... you get 4. then you add 2 & 4 ... you get 6.
The length of the x in the diagram is 12.
We can set up the following equation using the similar triangles that are created when you have an altitude in a right triangle.
If you subtract 16 from 25, you get 9, which is the length of the segment next to the 16.
x^2 = 16(9)
x^2 = 144
x = 12
We can use the cosine rule to find the third side:
c² = a² + b² -2abcos(C)
c = √(42² + 35² - 2(42)(35)cos(120)
c = 66.78
The answer is D.
Answer:
The answer is 1/8 because 1/2 as a decimal is 0.5 so do 1/2 and get 0.5 then you do 0.5 divided by 4 which is 0.125 and 0.125 as a fraction is 1/8
Step-by-step explanation:
It equals 72. If you have a problem like this again first start with the brackets, and the parentheses inside the brackets (if there is any). Then move onto the others outside the brackets like other parentheses (if there is any)
