area of a triangle is half the base times the height .5*22*28=308
yes
The altitude to the base of an isosceles triangle bisects it forming two right angled triangles (which are congruent). In either of those right angled triangles, the altitude forms one leg and half the base of the original triangle forms the other. So, tan(26) = Alt/11 or Alt = 11*tan(26) inches = 5.365 inches.
14.667 It would be proportional to the base of the first triangle. Find it by setting up a proportion: 18/22 = 12/x Cross multiply and solve for x. 18x = 264 x = about 14.67 cm
No. For a right angle triangle, the sum of the squares of the shorter sides equals the square of the longer side (the hypotenuse): 22 + 62 = 40 72 = 49
An isosceles triangle is in effect two right angled triangles joined together and in this case they have bases of 5 units and heights of 2 units so use Pythagoras' theorem to find the hypotenuse which will be the length of one of the equal legs of the isosceles triangle:- 52+22 = 29 and the square of this is about 5.385164807 or 5.385 to 3 dp

61. Divide the triangle down the middle, you have two right angled triangles with base 11 and height 60. Use pythagoras' theorem to get root(602+112) = 61.
If the vertex angle is 36 degrees then the two base angles must be 72 degrees each. An isosceles triangle can be thought of as being two conjoined right angled triangles. So by halving the base we can work out the hypotenuse with the trigonometry ratio for the cosine. cosine = adj/hyp and when rearranged hyp = adj/cosine hyp = 11/cosine 72 degrees = 35.59674775 Perimeter = 35.59674775+35.59674775+22 = 93.1934955 cm

The sum of interior angles of any triangle is 180 degrees. A right triangle is defined as a triangle having one angle that measures 90 degrees. Therefore, it follows that the sum of the remaining two angles will be 90 degrees 90-68=22 The third angle is 22 degrees
Since the triangle has a hypotenuse, it must be a right triangle. Therefore, the Pythagorean theorem applies, and the height of the triangle must be sq rt (32 - 22).
If the two equal sides are each 22 units in length then using Pythagoras' theorem to find its height it works out as: 54.644 square units rounded to 3 d.p.
