Question

5. Draw &DEF in which EF = 6 cm, E = 70 and F = 60. Find the measure of D​

Answer 1

Answer:

given :

angle E = 70

angle F = 60

SIDE EF = 6 CM

to find : angle d = ?

method :

70 + 60 + angle D = 180 ( total measure of triangle is 180)

130 + angle D = 180

angle D = 180 - 130

angle D = 50 cm
