Answer:

Step-by-step explanation:

Sum of angle in a triangle = 180°

<A+<B+<C = 180

Given <B = 50°

Substituting into the formula

<A+50+<C = 180

<A+<C = 180-50

<A+<C = 130°

Since the ∆ABC is an acute triangle, the angles <A and <C must be angles less than 90° since acute angles are angles less than 90°

The possible values of <A and <C that will be acute and give a sum of 130° are;

∠A= 58° and ∠C= 72°

∠A= 80° and ∠C= 50°

∠A= 60° and ∠C= 70°

You can see that all the Angles are less than 90° and their sum is 130°

b= - 8/11

Step-by-step explanation:

-4b-24=7b-16

-4b-24+24=7b-16+24

-4b=7b+8

-4b-7b=7b+8-7b

-11b=8

-11b/-11 = 8/-11

b= - 8/11

Arithmetic sequence

Step-by-step explanation:

It's Arithmetic sequence, because it's basically the list of integers that can be added, or subtracted by a same number every time. So, according to the following sequence shown, it shows that it's subtracting by [tex]6[/tex] every time.

Answer:

1. Rational

2. Rational

Hey You seem don't understand the Rational numbers and Irrational numbers

I will give you the example here

Irrational numbers are the numbers that has des keep going forever, like Pi,

will but keep going forever and has NO PARTERN. if it was like 1.4141414141414141414141414.....   thats not a Irational numbers

where Rational number are like: 1,3,-1,7/10......

Step-by-step explanation:

For angle BDG

The common angles are: Angle DBG, Angle DGB

The common sides are: DG, GB, BD

And for angle AEF

The common angles are: Angle EFA, Angle EAF

The common sides are: EF, FA, AE

FOR the BGD triangle, all sides are connected together, so, all of them are common and the angles as well

And the same exact thing with triangle AEF also

Hope it helps!

Step: Solvey=7x+12for y:

y=7x+12

Step: Substitute7x+12foryiny=7x+2:

y=7x+2

7x+12=7x+2

7x+12+−7x=7x+2+−7x(Add -7x to both sides)

12=2

12+−12=2+−12(Add -12 to both sides)

Answer:

20

Step-by-step explanation:

H+S=50

2H+4S=140

4H+4S=200

4H+4S=200-

2H+ 4S =140

2H=60

H=30

50-30=20

Given:

Each sheep has 4 legs and a chicken has 2 legs.

A farm boy counts total heads = 50

And number of legs = 140

To Find:

Number of sheep.

Solution:

Let the number of sheep in the farm = s

And the number of chicken in the farm = h

If the total number of heads = 50

s + h = 50 ------- (1)

If the total number of the legs = 140

Number of legs of 's' sheep = 4s

Number of legs of 'h' chicken = 2h

Therefore, 4s + 2h = 140

2s + h = 70 -------(2)

Subtract equation (1) from equation (2),

(2s + h) - (s + h) = 70 - 50

s = 20

Therefore, 20 sheep are in the farm.

Answer:

y = -4x + 7

Step-by-step explanation:

Since they are parallel they must have the same gradient which is -4

[tex]y = mx + c[/tex]

m = -4

x = 0

y = 7

7 = -4 × 0 + c

c = 7
