Showing algebraic support, find the value of x.

Travka [436]

Answer:

x = 52.5

Step-by-step explanation:

The triangle on the left has 2 congruent sides, thus is isosceles

The base angles of an isosceles triangle are also congruent, thus

x = $\frac{180-75}{2}$ = $\frac{105}{2}$ = 52.5

otez555 [7]

Answer:

X=7

Y=9

Step-by-step explanation:

.y=x+2

y = 2x - 5

Use equivalents y=y so you get:

X+2=2x-5

X-2x=-5-2

-x=-7

X=7

Y=x+2=7+2=9

A photocopier increased the sides of a square in the ratio 4:5.

Svetach [21]

Answer:

The sides are increased by a percentage of 25%

Step-by-step explanation:

Let

x -----> the length side of the original square

y ----> the length side of the increased square

we have

$\frac{x}{y} =\frac{4}{5}$

$y=\frac{5}{4}x$

$y=1.25x$

the increase is calculated by subtracting x from y

$y-x=1.25x-x=0.25x$

Remember that

$0.25=\frac{25}{100}=25\%$

therefore

The sides are increased by a percentage of 25%
