What is the measure of the missing angle? 31° 900

Mathematics
2 answers:
vladimir2022 [97]3 years ago
8 0

Step-by-step explanation:

Let the missing angle be ' x ' .

Now, Set up an equation and solve for x

\tt{x \degree + 90 \degree \: + 31 \degree = 180 \degree} { Sum of angles of a triangle }

⇢ \tt{x \degree + 121 \degree = 180 \degree}

⇢ \tt{ \: x \degree  = 180 \degree - 121 \degree}

⇢ \tt{x \degree = 59 \degree}

\red{ \boxed{ \boxed{ \text{Our \: final \: answer :  \boxed{ \underline{59 \degree}}}}}}

Hope I helped ! ツ

Have a wonderful day / night ! ♡

How many sides does a polygon have if the sum of the measures of the interior angles is 3960
anastassius [24]

Answer: the polygon has 20 sides.

Step-by-step explanation:

The formula for determining the sum of the measure of the interior angles in a regular polygon is expressed as (n - 2) × 180.

if the sum of the measures of the interior angles is 3960

degrees. This means that

(n - 2) × 180 = 3960

Expanding the brackets by applying the distributive property, it becomes

180n - 360 = 3960

180n = 3960 - 360

180n = 3600

Dividing both sides by 180, it becomes

n = 3600/180

n = 20

Answer:

The BLM presents awards to companies that minimize negative effects on the environment while mining natural resources. One such award is called the Hardrock Mineral Environmental Award. The BLM awards it to the mining company that has best fulfilled federal, state, or local requirements with little help from government agencies.

How does giving this award help the BLM more effectively manage land resources?

It prevents the companies from mining land resources such as gold and coal.

It informs companies about which minerals can be mined and which cannot be mined.

It encourages companies to follow rules set by government agencies.

It educates the companies about ways hard rock mining can destroy land resources.

Given the function f(x) = 6x^2 −13, what is f(-3)?
Naya [18.7K]
<h3>Answer: 41</h3>

Work Shown:

f(x) = 6x^2 - 13

f(x) = 6(x)^2 - 13

f(-3) = 6(-3)^2 - 13 ... replace every x with -3; use PEMDAS to simplify

f(-3) = 6(9) - 13

f(-3) = 54 - 13

f(-3) = 41

Noon to 3:05 elapsed time
GrogVix [38]
Noon is 12, I'm guessing you mean both of these at am, or both at pm. 12-3 is 3 hours, but there's 5 extra, so the elapsed time would be 3:05.
