Answer:

Step-by-step explanation:

Answer:

a) X would be marked 2 cm away from point A towards the point B

b) X would be marked 1.5 cm away from point P towards the point Q

Step-by-step explanation:

Data provided in the question:

Length of AB = 6 cm

Length of PQ = 6 cm

a) AX : AB 1 : 3

This means

on substituting the value of AB, we get

or

AX =

or

AX = 2 cm

Hence,

X would be marked 2 cm away from point A towards the point B

b) PX: XQ 1 :3

This means

or

⇒ 3PX = XQ   .............(1)

also,

PX + XQ = PQ

or

PX + XQ = 6 cm

substituting the value of XQ from (1)

PX + 3PX = 6 cm

or

4PX = 6 cm

or

PX =

or

PX = 1.5 cm

Hence,

X would be marked 1.5 cm away from point P towards the point Q

Answer:

a) X would be marked 2 cm away from point A towards the point B

b) X would be marked 1.5 cm away from point P towards the point Q

Step-by-step explanation:

Data provided in the question:

Length of AB = 6 cm

Length of PQ = 6 cm

a) AX : AB 1 : 3

This means

\frac{AX}{AB}=\frac{1}{3}

on substituting the value of AB, we get

\frac{AX}{6\ cm}=\frac{1}{3}

or

AX = \frac{6}{3}\ cm

or

AX = 2 cm

Hence,

X would be marked 2 cm away from point A towards the point B

b) PX: XQ 1 :3

This means

\frac{PX}{XQ}=\frac{1}{3}

or

⇒ 3PX = XQ   .............(1)

also,

PX + XQ = PQ

or

PX + XQ = 6 cm

substituting the value of XQ from (1)

PX + 3PX = 6 cm

or

4PX = 6 cm

or

PX = \frac{6}{4}\ cm

or

PX = 1.5 cm

Hence,

X would be marked 1.5 cm away from point P towards the point Q

A triangle has two sides measuring 16 and 21. The included angle is 116°. What is the length of the side opposite the 116° angle
aleksley [76]

Answer: A. 31.5

Step-by-step explanation:

Using law of cosine because it is side angle side

a=16

b=21

angle = 116

c^2=a^2+b^2-2ab cosC, let C be the angle given

c^2=(21)^2+(16)^2-2(16)(21) cos(116)

c^2=441+256-672 cos(116)

i used a ti-89 and answered the right side and got

(you can find a ti-89 simulator online, but for problems like this make sure it is in degree mode)

991.585

c^2=991.585

take square root of both sides

=31.4894, which if you round it up it would be 31.5, so the answer would be A

therefore:

a=16

b=21

c=31.5
