A is the point (10,4) and B is the point (4,-6).

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ A(\stackrel{x_1}{10}~,~\stackrel{y_1}{4})\qquad B(\stackrel{x_2}{4}~,~\stackrel{y_2}{-6}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{4+10}{2}~,~\cfrac{-6+4}{2} \right)\implies (7,-1) \\\\[-0.35em] \rule{34em}{0.25pt}$

For the right triangle NDO (look at the image) $\sin \angle OND= \frac{OD}{ND} = \frac{36}{200} = \frac{9}{50}$ .
Then $\angle OND=\sin^{-1} \frac{9}{50}$ .

Two numbers are in a ratio of 7:4 their sum is 220 find the bigger number

KiRa [710]

So to find the larger number:
1. Add the ratio together : 7+4 = 11
2. Find 1/11 of the number: 220 ÷ 11 = 20
3. Find 7/11 of a number ( bigger number): 20 × 7 = 140
and the smaller number will be 220 - 140 = 60
Hoped it helps:)

Find the value of x.

poizon [28]

We know that
Sum of angles in triangle = 180°
let third angle be Y

Now ,
60+74+Y = 180

=> 134 + Y = 180

=> Y = 46°

Now to find X

We know that angle made by straight line is 180°

So now ,
Third angle + x = 180°

=> 46 + x = 180

=> x = 180 -46
=> x = 134°
