Answer:
yes it is
Step-by-step explanation:
Draw a right triangle with horizontal base length 2, vertical length 3.
Use pythagorean thm to find length of hypotenuse:
Now use SOH CAH TOA to find correct trig ratios:
The opposite side is always the vertical side ----> 3
The adjacent side is always the horizontal side ---> 2
SOH ---> sin = opp/hyp
CAH ----> cos = adj/hyp
TOA -----> tan = opp/adj
Answer:
Step-by-step explanation:
∵ ABCD is a rhombus
∴ AC is ⊥ on BD
∴ ΔAEB is right angled triangle
If #peaches = x and #plums = y we can write the following equations:
x+y=15
0.89x + 0.39y = 8.85
and x and y are whole numbers.
converting the first to x=15-y and plugging it into the second, you get
0.89(15-y) + 0.39y = 8.85 =>
13.35 - 0.89y + 0.39y = 8.85 =>
4.5 = 0.5y =>
y = 9
so x = 15-9 = 6
