X = 20°
m∠H = 58°
m∠I = 71°
m∠J = 51°


Explanation:

The sum of the angles in a triangle is 180°.

(3x-2) + (4x-9) + (3x-9) = 180°

3x - 2 + 4x - 9 + 3x - 9 = 180°

10x - 20 = 180°

10x = 180° + 20°

x = 200°/10

x = 20°


m∠H:
= 3x - 2
= 3(20°) - 2
= 58°

m∠I:
= 4x - 9
= 4(20°) - 9
= 71°

m∠J:
= 3x - 9
= 3(20°) - 9
= 51°

Answer:

x = 16°

H = 46°

I = 55°

J = 39°

Step-by-step explanation:

Since the whole figure is 180°

Deduct 180 by the numbers mentioned above in order to find x.

180 - 2 - 9 - 9 = 160

3x + 4x + 3x = 10x

10 x = 160

x = 160 ÷ 10 = 16

Since we know what x is, we can find all the angles in the figure.

Angle at H = 3 x 16 - 2 = 46°

Angle at I = 4 x 16 - 9 = 55°

Angle at J = 3 x 16 - 9 = 39°

Work out the co ordinates of the midpoint of (-2,-1) and (-2,4)
s2008m [1.1K]

Answer:

(-2,\frac{3}{2})

Step-by-step explanation:

To find the midpoint, simply use the Midpoint Formula.

The Midpoint Formula states that for two points (x_1,y_1) and (x_2,y_2), the midpoint will be: (\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} ).

So, here, (x_1,y_1) = (-2, -1) and (x_2,y_2) = (-2, 4). The midpoint is then: (\frac{-2+(-2)}{2} ,\frac{-1+4}{2} )=(\frac{-4}{2} ,\frac{3}{2} )=(-2,\frac{3}{2})

Thus, the answer is (-2,\frac{3}{2}).

Hope this helps!

Two number cubes are rolled. Each number cube has sides numbered 1 through 6.
cricket20 [7]
There are a total of 6*6=36 outcomes (sums), of which 18 are odd, 18 are even, so the probability of getting an odd sum is 18/36
of the 36 outcomes, there are four fives and three tens, so the probability of getting a multiple of 5 is 7/36
but the four fives are also odd numbers, so we need to subtract 4/36
the result is: 18/36 +7/26 -4/36=21/36=7/12 =0.58333333

to see the total outcomes, Google image "two number cubes sum" or go to this website:
