$\huge \mathfrak \blue{Solution \: - }$

The formula for area of triangle is -

$\frac{1}{2} \times base \times height$

________________________________

So, the area of first triangle =

$\frac{1}{2} \times base \: \times height$

$\frac{1}{2} \times 4 \times 3$

$= \pink{6 \: units}$

________________________________

Area of second triangle =

$\frac{1}{2 } \times base \times height$

$\frac{1}{2} \times 4 \times 6$

$= \pink {12 \: units}$

________________________________

Area of second triangle - Area of first triangle

$= 12 - 6$

$= 6$

$\sf \underline\purple{The \: area \: increases \: by \: 6 \: square \: units.}$

What is the value of x?<br><br> What is the value of y?

Rudik [331]

Answer:

Y= 20

X= 25

Step-by-step explanation:

The angles of a triangle have to equal 180

80+60 = 140

180 - 140 = 40

40/2 = 20

Y = 20

The angles of a linear line split equal 180

2y is one side of it which we learned Y = 20 which makes that side 40

To find the other side just guess and check

6(25) = 150

150 - 10 = 140

So the 2y = 40 and the (6x-10) = 140

So yea boom done
