8 0

Answer:

yes, it is a right triangle.

Step-by-step explanation:

you could use the pythagorean theory to check:

$a^{2} + b^{2} = c^{2}$

(the hypotenuse is the longest side)

$17.5^{2} + 6^{2} = 18.5^{2}$

$306.25 + 36 = 342.25$

$342.25 = 342.25$

Solve: (x ÷ 4) + 8 = 38

Rainbow [258]

First you have to rewrite the equation:
(x ÷ 4) + 8 = 38

Second you have to write the division as fraction:
(¼x) + 8 = 38

Third you have to take off the unecessary bracket:

¼x + 8 = 38

Fourth multiply 8 and 38 by 4
x + 32 = 152

Fifth step move the constant to the right hand and change the sign.
x = 152 - 32

Then subtract:

x = 120

Hope this helps :))
