State if each triangle is a right triangle: *<br><br>13 in<br>2 in<br>12 in<br>​
olga_2 [115]

Answer:

It would be a obtuse triangle instead

Step-by-step explanation:

By using pythagorean and theorem (a^2 + b^2 = c^2)

So it would be 13^2___2^2 + 12^2

When you square them, you get 169___4 + 144

144 + 4 = 148, which is less than 169

SO it would be 169>148

So no, not a right triangle

Find the area of the iscoseles triangle first answer=brainliest
blsea [12.9K]

Answer:

60cm^{2}

Step-by-step explanation:

so first we need to find the height so by splitting the isosceles triangle into two right-angled triangles and then applying Pythagoras' Theorem to one of them.

h^{2} =13^{2} -5^{2}

h^{2} =169-25

h^{2} =144

h=\sqrt{144}

h=12

We now know the height of the triangle and can use this to go back and find the area of the isosceles triangle.

area of triangle = \frac{1}{2} x base x height

area of triangle = \frac{1}{2} x 10 x 12

area of triangle = 60
