Find the value of x:
slega [8]

Answer:

x = 20

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Using ΔAHC , then

∠ACH = 180 - (2x + 100) = 180 - 2x - 100 = 80 - 2x

∠ECD = ∠ACB ( vertical angles are congruent ), thus

∠ECD = ∠ACH + ∠HCB, that is

3x = 80 - 2x + x

3x = 80 - x ( add x to both sides )

4x = 80 ( divide both sides by 4 )

x = 20

Simplify the expression. 5/8*(18*3+(-22))+(-45)
lubasha [3.4K]
Using PEMDAS
(Parenthesis)(Exponents)(Multiplication/Division)(Addition/Subtration)
So:
\frac{5}{8} * ((54-22)-45) =  \frac{5}{8}*(32-45) =  \frac{5}{8}(-13)
=  \frac{-65}{8}= -8.125
