Answer: rounded to the tens is 10 the tens place is the one in 12.81 or like the one in 13.81
Step-by-step explanation:
Answer:
(3,2)
Step-by-step explanation:
Here's your given:
y = 4x - 10
y = 2
Because they both equal y, that means they equal each other:
2 = 4x - 10
Add 10 on both sides:
12 = 4x
Then, divide 4 on both sides:
3 = x
This represents the x coordinate.
Normally you would put this value into one of the equations to figure out y, but they already gave us that in the beginning:
y = 2
This represents the y coordinate.
Put the two values together to get: (3,2)
If you recall soh-cah-toa, tangent is equal to the opposite length divided by the adjacent length so it is true.
Answer: 3.83
Step-by-step explanation:
(2.24)(1.71)
=3.83
I think you just simply solve it
Add the three angles and set them to 180
4x-13+15+x+18=180
5x+20=180
5x=160
x=32
Then plug in to get A and C
A=4*32-13
A=115
C=32+18
C=50
