PLEASE ANSWER QUICK! I REALLY NEED HELP!

Katarina [22]

Answer:

a) Angle 1 = Value in degree = 95°

b)Angle 2 = Value in degree = 77°

c) Angle 3 = Value in degree = 85°

d) Angle 4 = Value in degree = 103°

Step-by-step explanation:

We use circle theorems to solve for this above question.

a) Angle 1 = Value in degree = 95°

Inscribed Angle is 1/2 of an Intercepted Arc

From the diagram, Angle 1 intersects at Arc B and Arc C

This means Angle 1 = (B + C)/ 2 =

Arc B = 100°

Arc C = 90°

Angle 1. = (100° + 90°)/ 2 = 190/ 2 = 95°

b)Angle 2 = Value in degree = 77°

From the diagram, Angle 2 intersects at Arc C and Arc D

Inscribed Angle is 1/2 of an Intercepted Arc

This means Angle 1 = (C+ D)/ 2

C = 90°

D = 64°

Angle 1. = (90° + 64°)/ 2 = 154/ 2 = 77°

c) Angle 3 = Value in degree = 85°

From the diagram, we can see that Angle 1 is opposite Angle 3, hence,

Opposite angles are supplementary which means their addition = 180°

Mathematically:.Angle 1 + Angle 3 = 180°

Angle 1 = 95°

95° + Angle 3 = 180°

Angle 3 = 180° - 95° = 85°

d) Angle 4 = Value in degree = 103°

From the diagram, we can see that Angle 2 is opposite Angle 4,

Hence,

Opposite angles are supplementary which means their addition = 180°

Mathematically:.Angle 2 + Angle 4 = 180°

Angle 2 = 77°

77° + Angle 3 = 180°

Angle 4 = 180° - 77° = 103°

Five whole numbers are written in order

xenn [34]

Answer:

The values of x and y is given by the equation $4x-y=20+y$ .

Step-by-step explanation:

Given : Five whole numbers are written in order 4 6 x y 10 , the mean and median of the five numbers are the same.

To find : The values of x and y ?

Solution :

Observations 4, 6, x, y, 10.

Mean is summation of observation divided by number of observation.

i.e. $m=\frac{\sum x_n}{n}$

$m=\frac{4+6+x+y+10}{5}$

$m=\frac{20+x+y}{5}$

Median is middle term of observations.

Median of odd terms $M=\frac{n+1}{2}^{th}$ term

$M=\frac{5+1}{2}^{th}$

$M=3^{rd}$ term

$M=x$

The mean and median of the five numbers are the same.

i.e. $\frac{20+x+y}{5}=x$

$20+x+y=5x$

$4x-y=20+y$

The values of x and y is given by the equation $4x-y=20+y$ .

I am honestly not sure about this answer... try Khan Academy. Or, try breaking it down into steps.

I hope this helped... sorry about that. I will try this concept soon. :)
