6 0

Step-by-step explanation:

the \: gradient \: of \: line \: a \: is

m =  \frac{4}{1 }  \\ m = 4

the \: gradient \: of \: line \: b \: is

m =  \frac{ - 2}{1}  \\ m =  - 2

Answer:

I'm not sure what you're looking for so I'll give you everything that I can about that triangle. The angles of the triangle are 90°, 66° and 24°. The size of the triangle are 8.22, 3.66, and the hypotenuse is 9

Step-by-step explanation:

angle A and angle B are complementary angles meaning they add up to 90° since this is a right triangle so 66 + 24 = 90 angle A is 24°. Now to find the measures of The legs of this triangle will use trigonometry more specifically the sign function.

b =  \sin(66)  =  \frac{b}{9}  \\ 9 \sin(66)  = b \\ 8.22 = b

a =  \sin(24)  =  \frac{a}{9}  \\ 9 \sin(24)  = a \\ 3.66 = a

by the Pythagorean theorem

{3.66}^{2}  +  {8.22}^{2}  =  {9}^{2}  \\ 80.9 = 81

5. A ladder leans against a building. The top of the ladder touches the building 10 feet above the ground. The foot of the
jek_recluse [69]

Answer:

68 degrees

Step-by-step explanation:

The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.

The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft.  Thus,

tan x = (opp side) / (adj side) = 10/4.  Using the inverse tangent function, we find that the angle in question is

arctan (10/4) = 68 degrees

The length of a rectangle is five times it’s width. If the perimeter of the rectangle is 120 yd, find it’s area
natita [175]

Answer:

Because the Length is 5 times the width, L(length) = 5w. You can use this information to update your perimeter.

P= L + W

P= 5w + w = 6w

P = 120, 120= 6w

120/6 = 6w/6

20 = w

L = 5w, L = 5(20) = 100

A = L x W, 100 x 20 = 2000

This means 2000 is the area
