WebArea of a Right Angled Triangle. If we have to find the area of a right-angled triangle then we can use the above formula directly by taking the two sides having the right angle one as the base and one as height. Here base = 3 cm and height = 4 cm. Area of triangle = 1/2 × 3 × 4. = 6 cm 2. Remark: If you take base as 4 cm and height as 3 cm ... WebForum. 10 grade maths.

Web30°+ 42° + x = 180°. x = 180°- (30° + 42°) x = 108°. And y is the exterior angle and the two opposite angles are ∠A and ∠B. So, ∠BCD = ∠A + ∠B (Exterior angle is equal to the sum of the two interior opposite angles). y = 30°+ 42°. y = 72°. We can also find it by linear pair axiom as BC is a ray on the line AD, so. Webthen we can write. (x-h) 2 + (y-r) 2 =r 2. further as the circle also touches y=mx. let us take tanθ=m then we have r=htan (θ/2) substituting the value of h in the equation we get a quadratic in r .. thus two possible radii and hence two circles. as both the circles pass through 9,6 this point should satisfy the equation .. now substitute x=9 ... iona heat network
