Sholpan [36]

Answer:

$z=\sqrt{80}$

Step-by-step explanation:

$y= \sqrt {16\times 4}$

$y= \sqrt {64}$

$y= 8$

By Pythagoras Theorem:

$z=\sqrt{4^2 +8^2}$

$z=\sqrt{16 + 64}$

$z=\sqrt{80}$

Find the values of x and y!!

riadik2000 [5.3K]

Answer:

1st option

Step-by-step explanation:

7x + 7 and 112 are vertically opposite angles and are congruent , then

7x + 7 = 112 ( subtract 7 from both sides )

7x = 105 ( divide both sides by 7 )

x = 15

4y and 112 are adjacent angles and sum to 180° , that is

4y + 112 = 180 ( subtract 112 from both sides )

4y = 68 ( divide both sides by 4 )

y = 17
