Find BC

Mathematics
2 answers:
Paha777 [63]3 years ago
7 0
The graphic says find BC and it says BC = 33 feet
Anyway, assuming the ladder is 34 feet, and makes an 82 degree angle,
cosine 82 degrees = adjacent / hypotenuse
adjacent = cosine 82 degrees * hypotenuse
adjacent = 0.13917 * 34
adjacent (or side BC) = <span> <span> <span> 4.73178 </span> </span> </span> feet

height (line AB) = sine (82 degrees) * hypotenuse (34 feet)
height (line AB) = 0.99027 * 34
height (line AB) = 33.67 feet

4. X varies directly with the square of y, where x&gt;0,
vampirchik [111]

Answer:

The value of y, when x = 48 is y = 12/5

Step-by-step explanation:

The given parameters are;

x is directly proportional to y

Where x > 0, y > 0

For x = 3. y = 5

Therefore, we have;

x ∝ a·y²

For ,x = 3, when y = 5, we have;

3 = a × 5² = 25·a

∴ a = 25/3

When x = 48, we have;

48 = 25/3×y²

y² = 3/25 × 48 = 144/25

y = √(144/25) = 12/5

y = 12/5

The value of y, when x = 48 is y = 12/5.

stira [4]

Answer:

x = 10

Step-by-step explanation:

130 = 8x + 50

<u>Step 1:  Solve for x</u>

130 - 50 = 8x + 50 - 50

80 / 8 = 8x / 8

10 = x

Answer:  x = 10
