Answer:

Step-by-step explanation:

Area of a triangle = 100 sq.cm

(1/2) * base * altitude = 100

(1/2) * 20 * altitude  = 100

                   altitude  = 100 *2 / 20 = 5 * 2 = 10 cm

Find the measure of angle a.
Ostrovityanka [42]

Answer:

a = 127°

Step-by-step explanation:

The 3 angles lie on a straight line and have a sum of 180°, that is

15° + a + 38° = 180°

53° + a = 180° ( subtract 53° from both sides )

a = 127°
