Ok so the hint is very useful and it says to divide the figure into 2 rectangles so if we do so the shorter rectangle's side lengths would be 9, 5, 9, and 5 because that last little bit of length is equal to the longer rectangle and it is also exactly half of 10. so to find the area of a rectangle the formula is a=length* width. so if you were to plug it in it would be a= 9*5 and it equals 45 so you have the area of the first rectangle. Then to find the area of the second rectangle you would do the same thing as the first one. and you would end up with 75. Then just add those two numbers up to get the area

6)
2(9+10) = 38
2(5+6) = 22

P = 38+22=60 in

14)
9 x 10 = 90
6 x 5 = 30
A = 90+50 = 140 in^2

Depending on a given set of conditions and the properties of triangles, any of these four outcomes is possible when constructing
Dennis_Churaev [7]

Answer:

Part A

the dotted line formes the thrid side of the triangle.

part B

The length is the unknon side increases while kepping the known side lenths fixed, measuremnt of anggle Z will increas. So, the tringle will not fir the given conditions anymore.

part c

If the length of he unknown side decrases while keeping h known side lengths fixed,the measure of angle will decrease so he tringle will not fit the given conditions anymore.

part D

You know the given conditions for the triangle are fixed you also know the unknown side length is fixed. What dose the this tell you angles adjacent to the unknown side.

part e

The given condiction are fixed and the unknown side lenghtis fixed, the angles adjacent to the unknown side must much also be fixed.

part f

Given two side lengths and the measurement of the angle between them, only one triangle can be constructed. Part G The length of the unknown side (c) is 9.76 centimeters

A point on the terminal side of an angle theta in standard position is (negative 24 comma 18 ). Find the exact value of each of
Vitek1552 [10]

Answer:

(I)Sin Θ=4/5

(II) Cos Θ =-3/5

(III) Tan Θ = -4/3

(IV) Cosec Θ = 5/4

(V) Sec Θ = -5/3

(VI) Cot Θ = -3/4

Step-by-step explanation:

(-24,18)

This lies in the second quadrant from the diagram.

Note that the angle is at the origin (0,0).

Using Pythagoras triples(18,24,30)

Hypotenuse = 30

Opposite=-24

Adjacent=18

(I)Sin Θ= Opposite/Hypotenuse

=-24/30=-4/5

Note: (Sine is Positive in the Second Quadrant)

Sin Θ =4/5

(II) Cos Θ = Adjacent/Hypotenuse

=18/30=3/5

Since Cosine is negative in the Second Quadrant

Cos Θ=-3/5

(III) Tan Θ = Opposite/Adjacent

Tan Θ = -24/18= -4/3

(IV) Cosec Θ = 1/Sin Θ = 5/4

(V) Sec Θ = 1/cos Θ = -5/4

(VI) Cot Θ = 1/tan Θ = -3/4
