Answer:a,c,d
Step-by-step explanation:
sum of all sides of triangle=180°
7x+13x+16x=180°
36x=180°
x=180°/36
x=5
angle D=7x
=7(5)
D=35°
angle E=13(x)
=13(5)
E=65°
angle F=16x
=16(5)
F=80°
angle D=35°
angle E=65°
angle F=80°
Answer:
D. 43°
Step-by-step explanation:
interior angle to 90°=90°
interior angle to 133°=47°
p=180°-47°-90°=43°
