Answer:
Step-by-step explanation:
a1=90-a2
a1=90-30=60
a2 is opposite 30 and opposite angles are equal so
a2=30
The sum of the angles of a triangle are equal to 180 degrees.
a2+a3+70=180
a3+30+70=180
a3=100=180
a3=80
So we want to see which number line shows the sum 1.5 + 2.5. We will see that the correct option is <u>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</u>
So the number line usually starts at 0 and goes to the first number, 1.5 in this case.
Then, it moves accordingly to the second number, 2.5 (so it will move 2.5 units to the right)
So the number line should start at 0 and move to the right until it meets 1.5 + 2.5 = 4.
From the options, the only that is correct is:
<u><em>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</em></u>

Answer:
<h3>2kg = mass</h3>
Step-by-step explanation:
<h3>What is the mass?</h3>
Mass is a body of matter without definite shape.
Use the Newton's second law of motion formula.
Note: 
<u>Given:</u>
- Force = 10N
- Acceleration = 5m/s
First thing you do is divide.
10/5=2
= 2kg (mass)
Therefore, the final answer is 2kg (mass).
I hope this helps, let me know if you have any questions.
