Question 433523: Hello There,
I need help solving for x and then classifying the triangle by its angles.(I already know how to classify them) My question is: Find the value of X.Then Classify the triangle by its angle measures.
angle#1:(2x+11) angle#2:x angle#3:94
What Ive tried: I set it up in a equation:94+x+(2x+11)=180
I combined like terms (2x+x)and i got 3x. Then i did 94+3x+11=180
Next,I tried 180-2=178...from that point on,..iv'e been stuck a while. And thats only number 1. Thank for helping ^_^

Question 433634: Hi everybody!
I just wanted to know, if you have a parallelogram or quadrilateral..or What ever,do you use 180 for the equal angles? Because heres what I did and I felt like i got the correct answer: PARALLELOGRAM:angle#1:138 angle#2:x angle#3:x angle#4:(3x+20)
First i set it up in an equation: 138=x+x+(3x+20)=180. Then i subtracted 138 from 138 and 180: 138-138+x+x+3x+20=180-138 and then I got 42. I combined like terms..i put it all together:5x+12=42. I subtracted 42-12 and got 30. Then i did 30/(divided)by 5x and got 6 as my final answer. :138+6+6=3x6+20=180..Is tht correct?..If not please explain why and how to do it correctly.^_^ please and Thankyou!!!

Question 433564: In a certain triangle, the measure of one angle is double the measure of a second angle but is 10 degrees less than the measure of the third angle. [The sum of the measures of three interior angles of a triangle is always 180 degrees.] What is the measure of each angle?
mine is
180 = x^2-z+y
as you can see, I am lost.

Question 433691: Hello, I am in Algebra 1(Integrated Algebra), as in the 9th grade class. We are doing right triangles and using Pythagorean Therom and ratios like tangent, sine, and cosine. I am confused on the following problem:

The legs of a right triangle measure 54 and 33. Find to the nearest
degree the measure of the smallest angle of the triangle.
Is the 54 the hypotenuse or either the opposite or adjacent leg? And, which angle is the smallest? I know it is not the one that measures 90 degrees. Thank you so much for your time! I would greatly appreciate it if you could get back to me before tomorrow! Thanks again!
