Hello.
Angle Theta is equal to: x² + y² = r² OR
40² + y² = 41²
1600 + y² = 1681
-1600 -1600
y² = 81
y = 9
x = 40, y = 9, r = 41
<span>cos θ= </span>
=
sin θ =
cot θ =
sec θ =
Hopefully it makes sense! :)
Answer:
46 cm²
Step-by-step explanation:
Given: ANB is a straight line
AN= 9 cm
NB= 5 cm
Are of rectangle( ANCD)= 36 cm²
Now finding the length of rectangle ANCD.
Lets assume the length of rectangle be "l"
Area of rectangle=
⇒
dividing both side by 9 cm.
∴
Hence, NC= 4 cm
Next, finding the area of triangle ΔNBC
Area of triangle=
⇒ Δ NBC=
∴Δ NBC= 10 cm²
We know, the area of ANCD= 36 cm²
∴ Area of ABCD= Area of rectangle+area of triangle
⇒Area of ABCD= 36+10
∴ Area of ABCD= 46 cm²

(The equation I used: 25(5.45)=136.25.If you went any further you wouldn't of gotten the answer.)
Hope This Helps!
Answer:
Joel had 120 dimes and 80 quarters.
Step-by-step explanation:
Given that Joel had 200 coins, which were dimes and quarters, and the total value was $ 32, to determine how many coins of each type he had, the following calculation must be performed:
0.25 - 0.10 = 0.15
200 x 0.10 = 20
32 - 20 = 12
12 / 0.15 = 80
200 - 80 = 120
(80 x 0.25) + (120 x 0.1) = X
20 + 12 = X
32 = X
Thus, Joel had 120 dimes and 80 quarters.
The equation is:
3x + 8 > 26 (or 2.6, I don’t know what the space means)
Hope this helped!
