Y + 0.5xy = x + 2; x = 1<br> How do you solve for y

vfiekz [6]

Step-by-step explanation:

replace the value of x with 1

y + 0.5 × 1 × y = 1 + 2

do the maths

y + 0.5y = 3

here the value of y is equal to 1. same goes for x, if we have no given value for them.

1.5y = 3

y = 3/1.5

y = 2

First

angle in front of c is 30°, so hypotenuse is equal to 2c

it's right triangle, so let's use Pythagorean theorem\

$(2c)^2=c^2+4^2\\4c^2=c^2+16\\3c^2=16\\\\c^2=\dfrac{16}{3} \\\\c=\dfrac{4}{\sqrt{3} } =\dfrac{4\sqrt{3} }{3 }$

Second

b - the base of the triangle, angles at the base are equal ⇒ cathets are equal

it's right triangle, so let's use Pythagorean theorem

$b^2=7^2+7^2\\b^2=49+49\\b=\sqrt{2\times49} =7\sqrt{2}$
