Answer:

The Y intercept is (0,7)

Step-by-step explanation:

If it is a y intercept, there will be a number in the y coordinate. For example, (x,y) if the point said (7,0) that would be the x intercept. Because it it (0,7) and in the y place that makes it a y intercept. I hope this helped :)

Triangle D E F is shown. The length of E F is 10, the length of D F is 7, and the length of D E is 12. What information relevant

Zarrin [17]

Answer:

34.98 square units.

Step-by-step explanation:

It is given that DEF is a triangle, EF=10, DF=7 and DE=12.

Information of sides of triangle is relevant to calculating area.

We should use Heron's formula.

According to Heron's formula, the area of triangle is

$A=\sqrt{s(s-a)(s-b)(s-c)}$

where,

$s=\dfrac{a+b+c}{2}$

For triangle DEF, let a=10, b=7 and c=12.

Now,

$s=\dfrac{10+7+12}{2}=\dfrac{29}{2}=14.5$

Area of triangle is

$A=\sqrt{14.5(14.5-10)(14.5-7)(14.5-12)}$

$A=\sqrt{14.5(4.5)(7.5)(2.5)}$

$A=\sqrt{1223.4375}$

$A=34.977671$

$A\approx 34.98$

Therefore, the area of triangle DEF is 34.98 square units.
