Step-by-step explanation:
1.
2. In this problem, when raising a whole fraction to a power, you must both raise the numerator and denominator to that power.
Answer:
Step-by-step explanation:
Recall that . Therefore,
In any right triangle:
- The sine of an angle is equal to its opposite side divided by the hypotenuse of the triangle (o/h)
- The cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle (a/h)
- The tangent of an angle is equal to its opposite side divided by its adjacent side (o/a)
From and , we know:
- 's opposite side is 1
- 's adjacent side is
- The hypotenuse of the triangle is 4
Therefore, the desired answer is .
Answer:
53.33
Step-by-step explanation:
finding area of ΔPAM
using similar triangles
16 = 12x; x =
ΔPAM = 4/3 * 4 * 1/2 = 16/6 = 8/3
ΔPAL = 4 * 12 * 1/2 = 24
24 + 8/3 = 80/3 (using fraction form for now, will round later)
since there are two ΔPLM (ΔLMU has same area since they are congruent)
we can multiply 80/3 by 2
80/3 * 2 = 160/3 = 53.33
Well c is the same exact problem but D could be it to because it easier to solve for x
The answer would be 7. The two minus signs cancel each other out and turn into a plus sign.
