Wich set of angles measure could be the measure of the interior angles of a triangle? 90,42 and 58. 60,60 and 60. 100,48 and 43.

4vir4ik [10]

Answer:

60°,60° and 60°.

Step-by-step explanation:

The sum of the interior angle of a triangle

=180°

So, let us test measured sets to get which of them could be the interior angles of a triangle.

The sum of the first measured set

= 90° + 42° + 58°

=190°

Also, the sum of the second measured set

= 60°+ 60° + 60°

=180°

The sum of the third measured set,

= 100°+ 48° + 43°

=191°

Finally, the sum of the fourth measured set

= 31° + 75°+ 70°

=176°

We can clearly conclude that, the measured set 60°,60°and 60° could only be the the set of interior angles of a triangle. Since it is the only set that add up to 180°

a bag contains 5 red skittles, 3 purple skittles, and 2 orange skittles.A skittle is removed and not replaced, then another skit

dybincka [34]

The probability of two independant events $P_a$ and $P_b$ can be found by multiplying the individual probabilities like so:
$P_t=P_{a}*P_b$

For each individual probability we can find the answer via a simplfied representation:
$P_x = \frac{wanted}{total}$

For the first skittle (red) we have:
$P_{red} = \frac{red}{total}=\frac{5}{10}=0.5$

For the second skittle (orange) we have:
$P_{orange} = \frac{2}{9} = 0.2222...$
**(Notice that the total is now NINE since we didn't put the first red one back in the bag.)

So:
$P_{total} = P_{red} \times P_{orange}$
$P_{total} = \frac{5}{10} \times \frac{2}{9}$
$P_{total} = \frac{10}{90}=\frac{1}{9} \approx 0.1111 \approx 11.11\%$

Solve x = 0.6x + 384

Gelneren [198K]

X = 0.6x + 384 |subtract 0.6x from both sides

0.4x = 384 |divide both sides by 0.4

x = 960
