.help me please
i accidentally pressed -4 btw

hint: the answer is not 3

-8

Step-by-step explanation:

All triangle angles must add up to 180.

If we look at the triangle, it has the angles of 40 degrees, and a right angle (90). If we add those together, we get 130.

So that means the top angle must be 50 degrees. Because 40+50+90=180.

So if the top angle is 50, the the other side must be 130. Again, because that is a 180 degree angle, going straight up.

So if we need to get 130, and the answers are not -4 or 3. Then the answer must be -8. Because 138+(-8)=130. Boom.

Hope this helped in some way. Stay safe, and have a good day!

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn
