Answer 1

Number 5. angles in a triangle add up to 180, u have one of them (24), and then u have 2 isocilies triangles which means they are both the same , 180-24=156.
156 devided by 2 =78, both of the angles are 78

Answer 2

I can't see the 5 the question properly but I'm sure 12) is 4 and 14) 70

Step-by-step explanation: 12) is( 4+4)÷2=4 and 14) 3+5+7=15 so, 5÷15=0.333333... then multiply it by210 you get 70

+ also on 15) just divide 5 by 2=2.5 and then divide 22 by 2.5 you get 8.8
