Answer:
B) obtuse
Step-by-step explanation:
Key skills needed: Triangle measure, Triangle Recognition
1) First we need to find the measure of the 3rd angle, and then we can determine what type of triangle it is.
2) The sum of all the interior angles in a triangle add up to 180 degrees. Let's say x is the measure of the 3rd angle.
This means --> [tex]20 + 30 + x = 180[/tex]
20 + 30 is 50, so --> [tex]50+ x = 180[/tex]
Subtract 50 from both sides and you will get x = 130
This means the 3rd angle measures 130 degrees.
3) Now, we have a triangle with a 20 degree angle, a 30 degree angle, and then a 130 degree angle.
An angle with measure with 130 degrees is an obtuse angle
(Keep in mind that an acute angle has a measure less than 90 degrees, a right angle measures 90 degrees, and an obtuse angle has a measure of more than 90 degrees - 130 is more than 90 so it is obtuse)
4) A triangle with 1 obtuse angle is an obtuse triangle, so Choose B) obtuse!!

What is 6 3/4 divided by 2 5/8?
Conversion a mixed number 6 3/4 to a improper fraction: 6 3/4 = 6 3/4 = 6 · 4 + 3/4 = 24 + 3/4 = 27/4.
To find new numerator:
Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4 = 24/4
Add the answer from previous step 24 to the numerator 3. New numerator is 24 + 3 = 27
Write a previous answer (new numerator 27) over the denominator 4.
Six and three quarters is twenty-seven quarters
Conversion a mixed number 2 5/8
to a improper fraction: 2 5/8 = 2 5/8 = 2 · 8 + 5/8 = 16 + 5/8 = 21/8
To find new numerator:
Multiply the whole number 2 by the denominator 8. Whole number 2 equally 2 * 8/8 = 16/8
Add the answer from previous step 16 to the numerator 5. New numerator is 16 + 5 = 21.
Write a previous answer (new numerator 21) over the denominator 8.
Two and five eighths is twenty-one eighths
Divide: 27/4 : 21/8 = 27/4 · 8/21 = 27 · 8/4 · 21 = 216/84 = 12 · 18 /12 · 7 = 18/7
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 21/
8 is 8/21) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 12 gives 18/7.
In words - twenty-seven quarters divided by twenty-one eighths = eighteen sevenths.
The solution of the expression [tex]6 \dfrac{3}{4}[/tex] divided by [tex]2 \dfrac{5}{8}[/tex] , which are in mixed fraction is [tex]\dfrac{18}{7}[/tex]
A collection of constants, variables connected using one or more arithmetic operator is called an expression.
The combination of a whole number and a proper fraction is called as mixed fraction.
The following expression can be simplified as:
Here, both the fraction are converted into improper fraction as[tex]\dfrac{27}{4}[/tex] and, [tex]\dfrac{21}{8}[/tex]
Now, the following expression is simplified as:
[tex]\dfrac{\dfrac{27}{4}}{\dfrac{21}{8}}[/tex],
Reciprocal the expression, so that the division sign changes to multiplication.
[tex]\dfrac{27}{4} \times \dfrac{8}{21}[/tex]
Thus, the solution will be [tex]\dfrac{18}{7}[/tex].

This diagram shows three small squares and two rectangles composed of 10 small squares, Jade says this diagram can represent 230. What does a small square represent for Jada? Name a number greater than 230 that can also represent.
Lin says this diagram can represent 2.3, what does a small square represent for Lin. Name a number of less than 2.3 that this diagram can also represent.
Answer:
Step-by-step explanation:
From the figure
A small square represents 10 for Jade's diagramA small square represents 1 for Lin's diagramFrom the figure, we have:
Rectangles = 2 (20 squares)
Square = 3
Represent 1 square with x.
So, the number is represented as:
[tex]Number = 20x + 3x[/tex]
[tex]Number = 23x[/tex]
Jade says the number represents 230.
So, we have:
[tex]23x = 230[/tex]
Divide through by 23
[tex]x = 10[/tex]
This means that:
A small square represents 10 for Jade's diagram
Lin says the number represents 23.
So, we have:
[tex]23x = 23[/tex]
Divide through by 23
[tex]x = 1[/tex]

Hope I help :)!explain how to make these couculations mentaly a. 99+54 b.244-99
PLEASE MARK BRAINLIEST!
Answer:
Use estimation
Step-by-step explanation:
A) 99 + 54
estimate that 99 is 100
estimate that 54 is 55
Add 100 and 55 together
100 + 55 = 155
Remember that you added 1 to 99 and 1 to 55
So you must subtract 2 from 155
155 - 2 = 153
Your answer is 153.
B) 244 - 99
estimate that 244 is 245
estimate that 99 is 100
Add 245 and 100 together
245 + 100 = 345
Remember that you added 1 to 245 and 1 to 99
So you must subtract 2 from 345
345 - 2 = 343
Your answer is 343.
Remember that you are doing all of this in your head!

Step-by-step explanation:
Answer:
well first you have to simplify them and then to add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical. If the indices or radicands are not the same, then you can not add or subtract the radicals.
