Answer:
x = 2
Step-by-step explanation:
2 + 2/x = 3
2/x = 1 Subtract 2 from both sides
x = 2 Multiply 2 to both sides
Answer:50
Step-by-step explanation:
it would be 50 because that’s a 90 degree angle and there is a 40 so 90-40=50
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 )

Step-by-step explanation:
markup = profit/cost * 100
Answer:
x = 4.5
Step-by-step explanation:
8x + 6 = 42 ( subtract 6 from both sides )
8x = 36 ( divide both sides by 8 )
x = 4.5
