Answer:
Please see attached picture for full solution.
Right angle= 90°
The sum of all the angles in a triangle is 180°.
1 to 4
150mm is the same as 15cm
15cm:60cm
both divisible by 15
1cm:4cm
1 to 4
It would be equal to 110 2/7
2. x = 1/4 ( 0.25)
4. y = 122, x = 42
6. x = 63, y = 8
8. is missing
10. 13.5 cm
12. x = 10.6
14. x = 5.45
Answer:
-20
Step-by-step explanation:
Do the math in the parenthesis first
(5-21) = -16
(3+1) = 4
Rewrite the problem
- 16 - 4= -20
The answer is -20
