What are you building when you use a distance formula
kirill115 [55]

Answer:

See below  

Step-by-step explanation:

In math, the distance formula gives us the distance between two

points, (x₁, y₁) and x₂, y₂):

d = \sqrt{(x _{2}-x_{1})^{2} +(y _{2}-y_{1})^{2}}

For example, in the triangle below, the distance between the points (1,5) and (-2, 1) is  

d = \sqrt{(1 - (-2))^{2} +(5-1)^{2}}

= \sqrt{3^{2} +4^{2}}

= \sqrt{9 + 16}

= \sqrt{25}

= 5

You are really using Pythagoras' Theorem to find the distance.

When using the distance formula, you are building a right triangle whose hypotenuse connects two given points.

Answer:

We also know that If two angles are complementary then  their sum is equal to 90°. So, two angles ∠1 & ∠2 are complementary.

Step-by-step explanation:

As BA is perpendicular to BC. So, angle ∠ABC is 90°.

We also know that If two angles are complementary then  their sum is equal to 90°. As ∠ABC is the sum of the ∠1 & ∠2. In other words, ∠1 & ∠2 are complementary. So, two angles ∠1 & ∠2 are complementary.

Lets prove this.

Given: BA ⊥ BC

Prove: ∠1 & ∠2 are complementary.

Statement                                                       Reasons

1. ∠1 & ∠2 are complementary                      1. Given

2. ∠1 + ∠2 = 90°                                             2. Def. of complementary angles

We need to simplify, then:

\frac{66}{90}=\frac{33}{45}=\frac{11}{15}

Mary Beth bought 45 oz of flour for her bakery. She used 17.3 oz to make a loaf of bread, and 0.83 oz for each muffin. How many
Marizza181 [45]

Answer:

11

Step-by-step explanation:

this equation can be derived from the question

45 oz - 17.3 oz - 0.83x oz = 18.57 oz

where x = number of muffins made

combine like terms

45 oz - 17.3 oz - 18.57 oz = 0.83x

9.13 = 0.83x

x = 9.13 / 0.83

x = 11
