Apr 25, 2009 · Total area of 120mm high isosceles triangle with 30º apex angle and 10mm corner radii = 5600sq.mm To work the problem as you define, we need one additional piece of information, such as the base, a side or an angle.

Apr 4, 2015 · Semi circle and triangle problem A semicircle and a isosceles triangle have the same base BC and the same area. Find the angle X in the triangle. The base of the triangle is BC and the angle X is at the corner B and C. Shown above are links to …

The easiest way to define an isosceles triangle is that it has two equal sides. In an isosceles triangle, we have two sides called the legs and a third side called the base. The angle located opposite the base is called the vertex. Sample A: The vertex angle B of isosceles triangle ABC is 120 degrees. Find the degree measure of each base angle ...

Jul 15, 2017 · Subtracting the area of the isosceles triangle from the area of the sector yields the area of the segment (i.e., the upper-shaded region in your diagram). Add that to half the circle's area. I get 78.6593 square units (rounded).

Nov 4, 2018 · A 20cm piece of wire is bent to form an isosceles triangle with base b. (So I labelled the two congruent sides as x each) a) show that the area of the triangle is given by a = 1/2 x sqrt( 100b^2 - 10b^3)

Jun 27, 2020 · c. The Isosceles triangle ABC. Just i want to make clear that according to the problem i need to calculate the area of the blue region? For me it is "Yes". Next the calculations [math] \int_{0.375}^{5.908}32(1+\sin\theta)^2 d\theta; =276.49 [/math]Now the area of the isosceles triangle

Nov 26, 2006 · The included angle of the two sides of a constant equal length "s" of an isosceles triangle is "θ" If θ is increasing at a rate of 1/2 radian per minute, find the rate of change of the area when θ=pi/6 The equation is Area=(1/2)s^2sinθ I cant get the dirivetive, the answer is dA/dt=(1/2)s^2cos(θ)(dθ/dt)

Jun 4, 2006 · hi, I need a little help finding the surface area of a tent shaped like a triangular prism. the floor of the tent would be a rectangle with the demensions 4ft by 6ft and the 2 triangular ends would be isosceles triandgles with base lengths of 4ft. The volume is 60ft cubed. I …

May 29, 2007 · Triangle ABC has AB = AC. It is circumscribed about a circle with a radius of 5 cm. what value of angle BAC produces the triangle of minium area. This is what i did: I know the formula should be : A = 1/2bh, but i have trouble taking the derviative of that, maybe i expressed the b/h ratios wrong. can some one help me plz

Nov 29, 2018 · From wiki: "Sometimes [an isosceles triangle] is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case."
