To solve this question, we must know the the angle sum property of a triangle. Therefore the value of ∠⁡⁣B is 85° when ∠A = 75° and ∠C=20° in △ABC

According to angle sum property of a triangle, the sum of all angles of a triangle is always 180 degree. It can never be more than or less than 180 degree. If two angles of a triangle is given then the third angle can be calculated by subtracting the sum of two angle from 180°

The sum of the three angles in a triangle = 180° , that is

∠ A + ∠ B + ∠ C = 180°

Substituting the given values in the given equation we get

75° + ∠ B + 20° = 180°

∠ B + 95° = 180°

subtracting 95° from both sides we get

∠ B = 85°

Therefore  the value of ∠⁡⁣B is 85° when ∠A = 75° and ∠C=20° in △ABC

Answer:

  a = √(b² +c² -2bc·cos(A))

  a = √(c² -b²)

Step-by-step explanation:

For sides a, b, c, and opposite angles A, B, C, the general form of the law of cosines is ...

  a² = b² + c² -2bc·cos(A)

An expression for 'a' can be written by taking the square root.

  a = √(b² +c² -2bc·cos(A))

__

If you recognize that cos(A) = b/c, then a substitution can be made:

  a = √(b² +c² -2(bc)(b/c)) = √(b² +c² -2b²)

  a = √(c² -b²) . . . . . . . same as the Pythagorean theorem

Measures of the given angles:

∠S = 25° and ∠R = 47°

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.

There are two main parts related to an angle - the arms and the vertex.

Given,

Measure of angle R is 3 degrees less than twice the measure of angle S

⇒ 2∠S - ∠R = 3°        

⇒ ∠R = 2∠S - 3°         ------(a)

Sum of R and S

⇒ ∠R + ∠S = 72°      

Substituting ∠R in terms of ∠S in above equation from equation (a)

2∠S - 3° + ∠S = 72°

3∠S - 3° = 72°

3∠S = 72° + 3°

3∠S = 75°

∠S = 75°/3

∠S = 25°

Substituting value of ∠S in equation (a)

∠R = 2 × 25° - 3°

∠R = 50° - 3°

∠R = 47°

Hence, ∠S = 25° and ∠R = 47° are the measures of given angles.

A linear function in slope intercept form is

y = mx + c

To find the equation, you need m and c. This can be found by substituting the points you have.

For example, 5 = -1(m) + c and -7 = 2(m) + c

From here, do simultaneous equations

c = m + 5

-7 = 2(m) + m + 5

3m = -7 -5

m = -4

c = m + 5

c = 1

Rewrite the equation: (This is your answer)

Step-by-step explanation:

The area of the shape in Step n is (n+1)²-2.

A recurring arrangement of numbers, forms, colours, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series.

From the given pattern,

Area of the shape in step 1 is 2 square centimeter

Area of the shape in step 2 is 7 square centimeter

Area of the shape in step 3 is 14 square centimeter

Here, the pattern is 2²-2=2

3²-2=7

4²-2=14

so, the general form is (n+1)²-2

Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees.

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.

Given is a triangle that has points Nigel, Mia, and Treasure Chest. The distance from Nigel to Mia is 100 meters. The angle between Treasure Chest, Nigel, and Mia is 65 degrees. The angle between Nigel, Mia, and Treasure Chest is 80 degrees.

Refer to the image attached.

It can be seen that Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees. We can conclude this from the fact that the longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle

Therefore, Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees.

Jude divided 15 pizzas bought into 1/9 pieces each. what is the total number of pizzas are we having?

This is a way of representing equations using real-world applications.

Given the expression 15 divided by 1/9, we can create a story to represent the expression. For instance;

Let the number of pizzas we have to be x

x = 15/(1/9)

x = 15 * 9/1

x = 135

Answer: P(7)=P(5)=12

Step-by-step explanation:

The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

A sack contains 7 milk and 5 dim chocolates. A sweet is chosen indiscriminately.

The total number of the sweets will be given as,

Total events = 7 + 5 = 12

The probability of choosing milk will be given as,

P = (7/12)

P = 0.5833

The probability of choosing not to milk will be given as,

P = (5/12)

P = 0.4167

The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.
