A geodesic dome is composed of two different types of triangular panels. One of these is an isosceles triangle. In one geodesic​ dome, the measure of the third angle is 70.5​° more than the measure of either of the two equal angles. Find the measure of the three angles

Two sides of a parallelogram are 50 cm and 70 cm long. Find the length of the shorter diagonal if a larger angle of the parallelogram measures 105°.

Determine if a trainle with sides of lengths 4cm,9cm ,and 10cm is a right triangle and explain how you know

2)Kira is participating in a cycle-a-thon to raise money for cancer research. The course that has been set up for participants to travel is in the shape of a triangle. Two of the angles of the course are 113 and 47, and the length of the side between these two angles is 4.1 km. For each kilometre that Kira cycles, she will raise $14.70 for cancer research. Determine how much money Kira raises if she cycles the course 3 times.
