For all triangles, the angle sum is 180°, therfore we can add all the angles up to solve x
54 + 55 + x + 74 =180
183 + x =180
X = 180 - 183
X = - 3 °
Don't worry, negative result is normal and possible.
See the attached picture:
6% = 1200
9% = 2400
12% = 3800
Measurement of one angle and length of one side I think
If the area of the room is 9x2 − 6x + 1 square feet, then the
length of one<span> side of the room is <span>(3x − 1) feet. </span></span>The correct answer between
all the choices given is the third choice or letter C. I am hoping that this
answer has satisfied your query and it will be able to help you in your
endeavor, and if you would like, feel free to ask another question.
