Suppose a triangle has sides a, b, and c let theta be the angle opposite the side of length a. If cos theta < 0 The statement that is true is <span>b^2+c^2>a^2. The answer is letter A.</span>
Answer:
X=140
Step-by-step explanation:
<em>Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees</em>
<em>The attachment you are showing us shows that we already know two angles</em>
<em>(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360. </em>
<em />
X+70+60+90=360
X=360-70-60-90
X=140
Answer:
9 1/3
Step-by-step explanation:
To evaluate 14 7/12 minus 5 1/4, recognize that the LCD here is 12 and that 5 1/4 must therefore be changed to 5 3/12.
Subtracting 5 3/12 from 14 7/12 yields 9 4/12, which, after reduction, is
9 1/3
