1/4+1/2=1/4+1/2=3/4
1/2=2/4
3/4 is the answer
Answer:
I can only get one page due to my device.
1. 105 degrees.
2. 75 degrees
3. 105 degrees
Parrallel lines and supplementary angles mean that all of the angles are either 75 or 105 degrees.
Answer: 232x
Step-by-step explanation: (8x)(33+2)
=(8x)(33)+(8x)(2)
=216x+16x
=232x
Answer:
find b: since the triangle is right angle triangle apply the Pythagorean theorem
c²+b²=d²
b²=d²-c²
b²=16²-12²
b²=256-144
b²=112
<h2>b=√112 = 4√7</h2>
the sum of the angle of the triangle=180
( in top Δ abd ) sin Ф=opp/hyp
sinФ=b/d=4√7/16= √7/4 radian
convert to degrees : √7/4 *180/π= 37.91 almost 38 degrees
<h2>which makes A= 38 degrees ( adjacent angles are equal when they have common side and do not overlap)</h2>
find a=?? apply law of cosine
a²= d^2 + c^2 − 2dc cosA
a²=16² + 12²-2(16)(12)cos38
a =√(16² + 12²-2(16)(12)cos38)
<h2>a=9.87 rounded to the nearest hundredth</h2>
(i hope it is right )
