Answer:

y = 107°

Step-by-step explanation:

As you can see from the markings on the triangle, this is an isosceles triangle (two sides are congruent).

An isosceles triangle has the base angles congruent too.

So at this point,

34 = x - 5

Solve for x,

34 = x - 5

x = 34 + 5

x = 39

Now, the total angle measure of triangle is 180°.

There are two angles ready to solve for y.

34 + 39 + y = 180

73 + y = 180

y = 180 - 73

y = 107°

Answer:y=28

Step-by-step explanation:

The image given is an isosceles triangle

An isosceles triangle is a triangle with (at least) two equal sides. An isosceles triangle therefore has both two equal sides and two equal angles.

Therefore 34° =(x-5)°.

And 34°+(x-5)°+4y°=180°

This implies;

34°+34°+4y°=180°

68°+4y°=180°

4y°=180°-68°

4y°=112°

4y°/4=112°/4

y=28

Use law of sines or law of cosines to find the length of side AB Please show work !!
scoray [572]

Answer:

AB = 11.3

Step-by-step explanation:

Given

The attached triangle

Required

Length AB

To do this, we make use of sine law which is represented as:

\frac{a}{\sin(a)} = \frac{b}{\sin(b)} = \frac{c}{\sin(c)}

So, we have:

\frac{15}{\sin(70)} = \frac{AB}{\sin(45)}

Make AB the subject

AB = \frac{15}{\sin(70)} * \sin(45)

AB = \frac{15}{0.9397} *0.7071

AB = 11.3

natali 33 [55]
First,multiply the -2 by everything in the brackets
so that's, -6x-(b-4x)+(x+6b)
then combine like terms
that's -6x-(7b-3x) which is
-3x-7b I believe

In 2013, the population of China was estimated to be 1,360,760,100. Round off the number of people 
Aleksandr [31]

Answer:

a) 1,360,760,000

b) 1,361,000,000

c) 1,400,000,000

d)  1,360,800,000

Step-by-step explanation:

We have to round off the given population number to certain digits.

The following are the rules to round of a number:

  1. First identify the digit to be rounded.
  2. If this digit is followed by 5,6,7,8,9 then we round up the number that is increase the digit by 1 and all the numbers to right becomes zero.
  3. If this digit is followed by 0,1,2,3,4 then we round down the number that is decrease the digit by 1 and all the numbers to right becomes zero.

a)  to the nearest thousand.

Thousands place: 0

Right Digit: 1

We round down the number

Rounded to the nearest 1,000 or t he thousands Place =  1,360,760,000

b)  to the nearest million

Millions place: 0

Right Digit: 7

We round up the number

Rounded to the nearest million places = 1,361,000,000

c)  to nearest hundred million

Hundred million place: 3

Right Digit: 6

We round up the number

Rounded to the nearest million places = 1,400,000,000

d)  to the nearest hundred thousand.

hundred thousand place: 7

Right Digit: 6

We round up the number

Rounded to the nearest million places = 1,360,800,000
