Find value of x. Round answer to nearest tenth.

Step-by-step explanation:

From the given right angle triangle,

The hypotenuse of the right angle triangle is 10.

With m∠x as the reference angle,

the adjacent side of the right angle triangle is 6

the opposite side of the right angle triangle is the unknown side.

To determine x, we would apply

the Cosine trigonometric ratio.

Cos θ = adjacent side/hypotenuse. Therefore,

Cosx = 6/10 = 0.6

x = Cos^-1(0.6)

x = 53.1° to the nearest tenth.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
