Question

construct a triangle DEF in which EF = 6cm angle E =70° and angle F=60° find the measure of angle D​

Answer 1

Answer:

I have constructed the triangle DEF in the attachment.

the measure of angle D is 50 degrees

Step-by-step explanation:

the sum of three angles in a triangle is 180 degree.

So, let the angle D be X

70+60+ x= 180

130+ x = 180

x = 180-130

x = 50
