You cannot: there is insufficient information.
Multiply half of the length of the base by the height. Just like any other triangle.
1/2*5*7 = 17.5 square cm
You can find it by using the Pythagorean theorem if you know the side and the base of triangle. In an isosceles triangle the median is also the altitude. The formula is: (The measure of the side length)^2 - (The measure of the one half of the base length )^2 = (The measure of the altitude)^2. Find the square root of the result that you'll have the measure of the altitude.
Is indeterminate.
Are of a triangle is (length of the base) times (height)/2 .
The 'base' is the length of the side that the triangle is standing on.The 'height' is the vertical distance from that line to the vertex atthe top of the triangle.
The square of the length of the base plus the square of the length of the height will equal the square of the length of the hypotenuse of your right triangle, per Pythagoras. Square the hypotenuse, subtract the square of the height, and then find the positive square root of that and you'll have the base of your right triangle.
pythagoreon thereom 34sq - 30sq = 256 sqrt = 16 base 16+16 = 32 half length of base = SQR(34^2 - 30^2) =SQR(1156-900) =SQR(256) =16 base length = 2x 16=32
The first is clearly not a suitable triangle.
The measurement of the angle of the triangle...supposing it is a triangle.
The area of any triangle is 1/2 of (length of the base) multiplied by (the height).Perhaps you can handle it from there.
The area of a triangle is (1/2) x (length of the base) x (height of the triangle). You ought to be able to handle it from this point.
