Answer:
Step-by-step explanation:
5. 17.25-8.25= 9
6. 7+8=15
7. 2*8=16 or 2*9=18
5) 9
6) 15
7) 16
5) 17.25 - (4.5 + 3.75)
Parenthesis comes first
4.5 + 3.75 = 8.25
17.25 - 8.25 = <u>9</u>
6) (14 - 7) + (3 + 5)
7 + (3 + 5)
7 + 8 = <u>15</u>
7) 4 ÷ 2 × 8
2 × 8 = <u>16</u>

The sum of all the angles of an isoceles triangle is 180°
So it's 50° + 2x° = 180°
50 + 2x = 180
2x = 180 - 50
2x = 130
x = 130/2
x = 65
