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:
1 : 5 2 : 10 3 : 15 4 : 20 5 : 25
Step-by-step explanation:
6n=$8.34, 8.34/6= 1.39 N=1.39
To solve, you must use order of operations. The acronym used is BEDMAS (brackets, exponents, division/multiplication, addition/subtraction), which is the order you solve in.
F 20÷4x5
=5x5
=25
T 10+10÷2
=10+5
=15
F 6+4×5
=6+20
=26

=9+2
=11</span>
