To find the area of the triangle, you will need to know the length of the base and there length of the height.

You can find both of these by using the circles that are given.

If the total length of the circles is 35 cm, then each circle has a length of 7 cm. If these are circles, then each circle has a height of 7 cm also.

A = 1/2 x b x h
1/2 x (4x7) x (2x7)
A = 196 square cm

Answer:

68.3 degrees

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan I = opp side / adj side

tan I = sqrt(82) / sqrt(13)

tan I = sqrt(82/13)

Taking the inverse tan of each side

tan ^-1 ( tan I) = tan ^-1( sqrt(82/13))

I = 68.2892

Rounding to the nearest tenth

I = 68.3 degrees
