This is a right triangle, the measure of angle A is 90 degrees.

First thing to do I guess is finding B and C.

tan^-1 (7/12) = 30 degrees

tan^-1 (12/7) = 60 degrees

60 + 30 = 90

180 - 90 = 90. Therefore angle A = 90 degrees

What is the distance between the points (-9,5) and (8,5)<br>

TiliK225 [7]

Answer:

17 units

Step-by-step explanation:

Use distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , to find the distance between (-9, 5) and (8, 5):

Let,

$(x_1, y_1) = (-9, 5)$

$(x_2, y_2) = (8, 5)$

Plug in the values into the distance formula:

$d = \sqrt{(8 - (-9))^2 + (5 - 5)^2}$

$d = \sqrt{(17)^2 + (0)^2}$

$d = \sqrt{(289 + 0)}$

$d = \sqrt{289}$

$d = 17$
