Best ResponseYou've already chosen the best response.0They must add up to 90 degrees, as a right angle is always 90 degrees.

Best ResponseYou've already chosen the best response.0So we add the two angles 30+3x and make it equal to 90, 3x+30 = 90

Best ResponseYou've already chosen the best response.0Now solve for x to find the angle

Best ResponseYou've already chosen the best response.0Can you please show you work? I know you expect me to do the work, but that will not benefit you, if you don't know how to do the algebra you are more than welcome to ask, don't worry about being wrong.

Best ResponseYou've already chosen the best response.0When we are doing algebra, we use the opposite property of what exists to move things. Say we're given something like \[5x=30\] notice the x is attached to the 5 that implies x is being multiplied by 5 as such \[5 \times x = 30\] So we say mhm, alright so what can we do to move the 5 away from x so we can get x alone, and also note what you do to one side you must always do it to the other. So we divide both sides by 5...oh I see you know how to do algebra but your arithmetic is wrong.

Best ResponseYou've already chosen the best response.0Ned wrote the following statement: "You can only draw one unique isosceles triangle that contains an angle of 80°." Which statement is true? Ned is correct, because only one unique triangle can be drawn with the given information. Ned is incorrect, because the triangle described cannot be drawn with the given information. Ned is incorrect, because more than one triangle can be drawn with the given information.

Best ResponseYou've already chosen the best response.0Linda described four triangles as shown below: Triangle A: All sides have length 7 cm. Triangle B: All angles measure 60°. Triangle C: Two sides have length 8 cm, and the included angle measures 60°. Triangle D: Base has length 8 cm, and base angles measure 55°. Which triangle is not a unique triangle? Triangle A Triangle B Triangle C Triangle D

Best ResponseYou've already chosen the best response.0So what you mentioned is a equilateral triangle as all angles are the same.
