ANSWER ASAP FOR BRAINIEST AND 100 POINT ASAP<br> Find the value of x in the triangle.
deff fn [24]

The total measure of all the angles in a triangle is 180°.

Since there is already a 90° angle, the other 2 angles must also add up to 90°.

The only answer that fits is x = 9.

Check:

9x7 = 63°

3x9 = 27°

Add up = 90°

Find the coordinates of the midpoint of the segment whose endpoints are H(10, 1) and K(4, 7).
Oliga [24]

The formula of a midpoint of a segment AB:

A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)

We have:

H(10; 1); K(4; 7)

substitute:

M_{HK}\left(\dfrac{10+4}{2};\ \dfrac{1+7}{2}\right)\to M_{HK}\left(\dfrac{14}{2};\ \dfrac{8}{2}\right)\to M_{HK}(7;\ 4)

Answer: (7, 4)
