Use Your Knowledge Of The Triangle Sum Theory To Solve For X. Then Solve For L.help Plss

Answers

Answer 1

Answer:

X= 15

K=45

Step-by-step explanation:

The Triangle Sum Theory means that every interior angle of a triangle sums up to 180. My first approach was to put 169 as x but that isn’t correct. That is because a triangle’s smallest angles have to add up to be more than the biggest angle. Ex (10, 5, 7 that is a triangle because the sum of 5+7 is more than 10) So as you can see there are x’s next to the other numbers. That is because x needs to be able to multiply with the other numbers and stand on it’s own and add up to 180. So this would be the equation: X+8•X+3•X=180. You should find that 15 makes everything add up to 180. Now knowing x is 15 now we know that 3x is equal to 45. So k=45 That is how you solve this tricky question. Hope this helps! ❤️

Answers

Answer:

see explanation

Step-by-step explanation:

∠ 1 = 42° ( alternate to ∠ FCD )

∠ CDF = 180° - 157° = 23° ( adjacent angles are supplementary )

∠ 2 = 23° ( alternate to ∠ CDF )

∠ 3 = 180° - (42 + 23)° = 180° - 65° = 115° ( sum of angles in triangle )

Thus

∠ 1 = 42°, ∠ 2 = 23°, ∠ 3 = 115°

Answers

Answer:

130'²

Step-by-step explanation:

step 1) work out area of whole trapezium:

((a+b) x h) / 2

a and b are the two parallel sides

h is the perpendicular height (8)

a = 4+4+3 = 11

b = 23

a + b = 11 + 23 = 34

(a + b) x h = 34 x 8 = 272

272 / 2 = 136²

step 2) work out the area of rectangle

2 x 3 = 6²

step 3) take area of rectangle away from area of whole trapezium

136 - 6 = 130

Matthew went to his local gym to work out. The ratio of his time

Answers

Answer:

1 hour and 40 minnutes.

Step-by-step explanation:

If you mean 45 minutes, then here you go:

First, take 5 minutes from the 45 and give it to the 55, which will make the 55 into 60 and the 45 into 40. Now, you have 60 and 40, which equals 100 minutes, or 1 hour and 40 minutes.

A taxi driver's flat rate of $3 plus an additional $0.05 per mile car will only take taxi home if cost is under $10 under otherwise he will take the bus Carlos 15 miles from home explain how to write and solve an inequality determining if Carl will take the taxi for a bus

Answers

Step-by-step explanation:

we can model the expression for the inequality as

given the flat rate is $3

let the additional mile be x

hence

3+0.05x<10

step two:

let us proceed to solve for x

3+0.05x<10

0.05x<10-3

0.05x<7

divide both sides by 0.05

x<7/0.05

x<140    

let us plug in 15 into the expression and see if the cost is under $10

3+0.05(15)<10

3+0.75<10

3.75<10

from the analysis, carl will have to take the taxi since cost is less than $10 i.e $3.75

Answer:

The inequality representing the situation is 0.5x + 3 < 10.

Use inverse operations and properties of inequality to solve.

Find that x < 14.

Carl lives 15 miles from home, so he will take a bus.
