Given triangle ABC is similar to triangle DEF, angle A measures 30 degrees, and angle F measures 50 degrees, what is the measure
Alona [7]

Answer:

100 degrees

Step-by-step explanation:

Since triangle ABC is similar to triangle DEF, their angles are basically the same.

All angles of a triangle have to add up to 180.

We are already given two angles: 30 and 50

Add them together: 30 + 50 = 80

Now we subtract the number from 180

180 - 80 = 100

The remaining angle has to be 100 degrees

<h2><u>ᎪꪀsωꫀᏒ</u></h2>

➪x= 13

Step-by-step explanation:

49+59+5x+7=180

115+5x= 180

5x = 180-115

5x= 65

x= 65/5

x= 13
