The measures of angle ABC are given by the expression on the table (shown below)

amid [387]

Answer:

<A = ( 4 * 32 - 13 ) = 115

<C = ( x + 18 ) = 50

Step-by-step explanation:

(4x - 13 ) + 15 + ( x + 18 ) = 180 ( because the total angle of a triangle is 180)

5x + 20 = 180

5x = 160

x = 32

What is the value of z in the equation 2(4z − 3 − 1) = 166 − 46?

shepuryov [24]

Refine $2(4z-3-1)$

$= 2(4z-4)$

Refine : $166 - 16 = 120$

therefore:

$2(z-4) = 120$

Divide both sides by 2 :

$\frac{2(z-4)}{2} = \frac{120}{2}$

$4z-4 = 60$

add 4 to both sides:

$4z-4+4 = 60+4$

$4z = 64$

Divide both sides by 4 :

$\frac{4z}{4} = \frac{64}{4}$

$z = 16$

hope this helps!
