Answer:
x+ (x+1) = 55
27, 28
Step-by-step explanation:
Let x = first number
x+1 is the next consecutive number
x+ (x+1) = 55
Combine like terms
2x+1 = 55
Subtract 1 from each side
2x+1-1 = 55-1
2x = 54
Divide by 2
2x/2 = 54/2
x = 27
The numbers are 27 and 28

Answer:
The answer to your question is below
Step-by-step explanation:
Data
A (4 , -3)
r = ?
sin = ?
cos = ?
tan = ?
Process
1.- Plot the point
This point is in the fourth quadrangle
2.- Calculate r
We have the Opposite side and the Adjacent side
tan Ф = -3/4
tan⁻¹ Ф = Ф = 323.1
Ф = 323.1°
3.- sinФ =
Calculate the hypotenuse
c² = 4² + (-3)²
c² = 16 + 9
c² = 25
c = 5
sinФ = -3/5
cos Ф = 4/5
tan Ф = -3/4
Answer:
54.28 cm²
Step-by-step explanation:
Area rectangle = 10 x 4 = 40 cm²
Area semicircle = 1/2(π(2²)) = 1/2(π(4)) = 2π ≈ 6.28 cm²
Area triangle = 1/2(4 x (10-14)) = 1/2( 4 x 4) = 2 x 4 = 8 cm²
Total Area = 40 cm² + 6.28 cm² + 8 cm² = 54.28 cm²
