Answer:

  A = 51.3°, B = 90°, C = 38.7°

Step-by-step explanation:

The given lengths satisfy the Pythagorean theorem:

  (√41)² = 4² +5²   ⇒   41 = 16 +25

so we know the triangle is a right triangle. The right angle is opposite the longest side, so is angle B, opposite side AC.

The remaining angles can be found using trig functions. For example, we know ...

  tan(A) = BC/AB = 5/4

  A = arctan(5/4) ≈ 51.3°

Then the other acute angle is ...

  C = 90° -51.3° = 38.7°

Angles A, B, C are ...

  (A, B, C) = (51.3°, 90°, 38.7°)

If (a+b)^2=54, and (a-b)^=46, then a^2+b^2=?
erastovalidia [21]

(a+b)^2 =a^2 +b^2 + 2ab = 54~~~.....(i)\\\\(a-b)^2 = a^2 +b^2 -2ab = 46~~~.....(i)\\\\\\(i)+(ii):\\\\(a+b)^2 +(a-b)^2  = 54+46\\\\\implies a^2 +b^2 + 2ab + a^2 +b^2 - 2ab =100\\\\\implies 2a^2 +2b^2 =100\\\\ \\\implies 2(a^2 +b^2) =100\\\\\implies a^2 +b^2 = \dfrac{100}2 = 50

If a spinner for a game is spun once, there is a 25% chance it will land on
bonufazy [111]

Answer:

Pr = 0.6

Step-by-step explanation:

Given

Let

O \to Orange

So:

P(O) = 25\% --- probability of O

n=2 --- Number of spin

Using the complement rule, the probability that a spin will not land on orange is:

P(O') = 1 - P(O)

P(O') = 1 - 25\%

Express as decimal

P(O') = 1 - 0.25

P(O') = 0.75

On two spins, the probability that it will not land on orange is:

Pr = P(O') * P(O')

So, we have:

Pr = 0.75* 0.75

Pr = 0.5625

<em></em>Pr = 0.6<em> --- approximated</em>
