Answer:
Use the cross technique if it’s name like that in English but , I wish you can understand it from what I‘ve written .
1) You need to solve t -

2) Then solve f

3) As it's constant it is<span> still 10m/s
4) You need to </span><span>use the</span> time from part 1 times 10m/s
5) Use Pythagorean theorem with <span>10m/s and vf
I am pretty sure it will help you.</span>
Answer:
∠1 = 40
Step-by-step explanation:
So due to the alternate interior angles theorem, angle 1 and angle 2 equal each other so:
2x + 20 = 3x + 10
subtract 2x from both sides
20 = x + 10
subtract 10 from both sides
10 = x
Now input 10 into the equation
2(10) + 20
20 + 20
40
I think it’s 10 sorry if it’s wrong
