we know that

A linear pair is a pair of adjacent, supplementary angles. Adjacent means next to each other, and supplementary means that the measures of the two angles add up to equal 180 degrees

So

case a) ∠SRT and ∠TRV

∠SRT +∠TRV=180°----> by supplementary angles

therefore

∠SRT and ∠TRV is a linear pair

case b) ∠SRT and ∠TRU

∠SRT +∠TRU > 180°----> are not supplementary angles

therefore

∠SRT and ∠TRU is not a linear pair

case c) ∠VRW and ∠WRS

∠VRW +∠WRS = 180°----> by supplementary angles

therefore

∠VRW and ∠WRS is a linear pair

case d) ∠VRU and ∠URS

∠VRU +∠URS = 180°----> by supplementary angles

therefore

∠VRU and ∠URS is a linear pair

case e) ∠URW and ∠WRS

∠SRT +∠TRU < 180°----> are not supplementary angles

therefore

∠URW and ∠WRS is not a linear pair

Answer:

if ∠Q=∠R

draw an angular bisector from P to QR in which it intersect wit Qr at point S

now we have two triangle : QPS and RSP

in which angle : QPS=RPS ( PS is angular bisector)

and we have angle Q and angle R are equal

and PS is common side

this makes triangle QPS and RSP are congruent by AAS(angle angle side)

which also means that pQ=PR ( proved)

Answer:

First you would make 62% into \frac{62}{100}

7893+82-\frac{62}{100}

Than you would do 7893+82 which is 7975

7975-\frac{62}{100}

You would than simplify \frac{62}{100} which is \frac{31}{50}

7975- \frac{31}{50}

<u><em>Therefore your answer will be </em></u><em />\frac{398719}{50}<u><em> or in decimal form it will be </em></u><em />7974.38<em />

Hope that helps :>

Create your own system of 2 equations word problem. Answer it with full step by step explanation. Help and thank you. ​
mr_godi [17]

Answer:

<h2>30</h2>

Step-by-step explanation:

<h3>to understand the steps</h3><h3>you need to know about:</h3>
  • system of linear equation
  • word problems
  • PEMDAS

first step

let's create the equation word problem

<h3>my mother's current age is four times the sum of the ages of my two sisters. After 5 years, my mother's age will be double the sum of the ages of my two sisters. What is the current age of my mother? (imaginary problem)</h3>

let's solve

let my mother's and sister's age be x and y respectively

according to the first condition,x=4y....(I)

according to the 2nd condition,x+5=2(y+5×2).....(ii)

so the system of linear equations is

x=4y

x+5=2(y+5×2)

gets from the second equation

x+5=2(y+10)

x+5=2y+20

4y+5=2y+20 (as x=4y)

2y=15

y=7.5

so the age of mother is

x=4.(7.5)

x=30
