Add 1/2 to both sides.

-\dfrac{1}{2} + p + \dfrac{1}{2} = \dfrac{5}{8} + \dfrac{1}{2}

p = \dfrac{5}{8} + \dfrac{4}{8}

p = \dfrac{9}{8}

Find the length of x exactly. Brainly!!
NNADVOKAT [17]

Answer:

x = 7

Step-by-step explanation:

We can tell by looking at this triangle that this is a <u>45 45 90 triangle.</u>

In this situation, the hypotenuse is x\sqrt{2} and the legs are both x.So if we look at the hypotenuse, we can tell that x, or the leg of the triangle, is 7.

45 45 90 triangles: This is a special triangle in which the angles of the triangle are 45 45 and 90 degrees. This means that the hypotenuse will be x\sqrt{2} and the legs of the triangle will be x. You can usually use the Pythagorean theorem to solve the missing sides.
