Answer: The fourth option, 54°
Step-by-step explanation:
In the graph we can see that we have a triangle rectangle.
I will call each angle as the letter where it is located, the bottom angle is D, the upper left angle is C and the upper right angle is B (this last one is the angle we want to find)
This means that if the bottom angle, the angle located at D, is equal to 36°, we have that the angle located at C is equal to 90°.
And as you know, the sum of all the internal angles of a triangle must be equal to 180°, so we have:
D + C + B = 180°
90° + 36° + B = 180°
B = 180° - 90° - 36° = 54°
The correct option is the fourth one.
Answer:
1/40
Step-by-step explanation:
You have to find the amount of distance they traveled since the start of the journey. 3/5 + 3/8 is 39/40. How did we get that, you may ask?
We need to find a number that both 5 and 8 have to make. That can be 40. But how we made 5 and 8 40, we need to do the same to the top numbers. So 39/40 when we add them up. Finally, we need to substract that from the whole, and this gets you 1/40. Hope this helps.
Have a wonderful day, my friend.
Answer:
enter t= 12
Step-by-step explanation:
I think it helps
slope =(y2-y1)/(x2-x1)
m=(-1-5)/(1--1)
m=-6/2
m=-3
y-y1=m(x-x1) point slope form
y-5 = -3 (x--1)
y-5 = -3 (x+1)
distribute
y-5 = -3x -3
add 5 to each side
y = -3x+2
