Answer:
70
Step-by-step explanation:
I would do 40 + 30 = 70
180-70 = 110
110 is the last angle bc all angles add to 180 in a triangle

Divide 700 by 25
Answer:
32
Step-by-step explanation:
Side AD = 4
9-5=4
Side DC = 13
a^2+b^2=c^2
5^2+12^2=c^2
25+144=c^2
169=c^2
13=c
Side AC = 15
a^2+b^2=c^2
9^2+12^2=c^2
81+144=c^2
225=c^2
15=c
