Answer:

angel A = 25°

angel B = 58°

Step-by-step explanation:

ACD + ACB = 180°

83° + ACB = 180°

ACB = 180° - 83°

ACB = 97°

ACB + angel B + angel A = 180°

97° + 4x + 1° + 9x + 4° = 180°

13x = 180° - 102°

13x = 78°

x = 78°/13

x = 6

angel A = 4x + 1°

angel A = 4(6) + 1°

angel A = 24 + 1°

angel A = 25°

angel B = 9x + 4°

angel B = 9(6) + 4°

angel B = 54 + 4°

angel B = 58°

Find the length of the diagonal, round to the nearest tenth (( please answer, ill give brainliest))​
Lilit [14]

Answer:

Length of diagonal in the first top figure is 13 yd

Okay for this one, the formula of a diagonal in a cuboid is the root of sum of squares

length, breadth and height

so

D = root of 12^2 + 4^2 + 3^2

D = root of 144 + 16 + 9

D = root 169

D = 13yd

Length of diagonal in the bottom figure is 10.77 which is 10.8m

For this one, you have to find the diameter of base first

Since radius of the base is 5 diameter = 10

Since its a right angled triangle, Hypotenuse square = sum of sides square

Diagonal^2 = 10^2 + 4^2

D^2 = 100 + 16

D^2 = 116

D = root 116

D = 10.77

D = 10.8 m

Given f (x) = 3x - 5 find f (x - 2)
antiseptic1488 [7]

Answer:

3x-11

Step-by-step explanation:

f (x) = 3x - 5

f(x-2)

Replace x in the function with x-2

f (x-2) = 3(x-2) - 5

           =3x-6 -5

           =3x-11
