Answer:
This is an Obtuse triangle.
Step-by-step explanation:
A Equilateral Triangle is a triangle where all sides are equal. Here all sides are different so it is not an Equilateral Triangle.
Isosceles triangle is a triangle that has 2 sides that are equal. Here all sides are different therefore this is not an Isosceles triangle.
A right angled triangle is a triangle whose sides satisfy the following equality.
Lets say A triangle has sides a, b and c. Where c is the highest value.
Then, 
Lets substitute the values to the above equation to see whether it the triangle we are given satisfies the above equality,
= 
=
Therefore, ≠![17^{2}So it is not a Right Angled Triangle.If the sum of squares of the shorter sides is greater than the square of the longer side then it is an Acute angle if not it is an obtuse angle.[tex]7^{2} +15^{2}](https://tex.z-dn.net/?f=17%5E%7B2%7D%3C%2Fp%3E%3Cp%3ESo%20it%20is%20not%20a%20Right%20Angled%20Triangle.%3C%2Fp%3E%3Cp%3EIf%20the%20sum%20of%20squares%20of%20the%20shorter%20sides%20is%20greater%20than%20the%20square%20of%20the%20longer%20side%20then%20it%20is%20an%20Acute%20angle%20if%20not%20it%20is%20an%20obtuse%20angle.%3C%2Fp%3E%3Cp%3E%5Btex%5D7%5E%7B2%7D%20%2B15%5E%7B2%7D)

Therefore, This is an Obtuse triangle.
Answer:
It is 4x + 4y.
Step-by-step explanation:
All you have to do is add all of the y's toghther and then add all of the x's toghther.
Since the measure of angles adds up to 180, you should add all of the known angles up and subtract from 180 to find the missing angle. For example: 47+69=116
and
180-116=64 so the measure of the missing angle is 64 degrees
85+42= 127
180-127=53 s the measure of the missing angle is 53
Answer:
x is 37°.
Step-by-step explanation:
Since a straight line is 180°, all we need to do is add 74 and 69, to get 143, and just subtract 143 from 180 to get 37.
Hope this helped you!! :]
2x+3x=5x
the +10-10 cancel each other out so it's just 80
5x+80=180
5x=180-80
5x=100
x=20
