Answer:
A. 904.32 ft cubed
Step-by-step explanation:
Answer:
Width = 6.45 cm
Length = 8.6 cm
Step-by-step explanation:
the sides of a rectangle are such that the width is three-quarters of the length. if the diagonal is 15cm find the length and the width.
From the question,
W = 3/4L
W = 3L/4
When given diagonal,
W² + L² = D²
Where, D = Diagonal
W = Width
L = Length
Hence, Substituting 3L/4 for W
(3L/4)² + L² = 15²
9L²/16 + L² = 225
L²(9/16 + 1) = 225
Divide both side by 9/16 + 1
L² = 225/(9/16 + 1)
Square root both side
L = √225/(9/16 + 1)
L = 15/3/4 + 1
L = 15 ÷ 1 3/4
L = 15 ÷ 7/4
L = 15 × 4/7
L = 8.6cm
W = 3L/4
W = 3(8.6)/4
W = 6.45cm
Firstly we need to find m<DNY
m<DNY=(60+90)÷2=75
N9w we can find m<KNY
m<KNY+m<DNY=180°(Because these are adjacent corners)
m<KNY+75°=180°
m<KNY=180°-75°
m<KNY=105°
If its negative to negative the number will be positive if its two positives I will be positive and the higher number of the problem decides weither its positive or negative then u add like normal
