Answer:
Parameter is 56
Step-by-step explanation:
You can isolate y on both sides, getting:
2x-17=y and x-10=y
Then, make the two y equal each other, and solve the equation
2x-17=x-10
The answer would be x=7.
then, plut in the amount into one of the equations:
x-y=10
7-y=10
y=-3
T
Therefore, the answer is x=7 and y = -3, or (7,-3)
<span>2x + 18 - 1 = 33
First combine like terms on the left side.
2x + 17 = 33
Now subtract 17 from both sides.
2x = 16
Lastly, divide both sides by 2.
x = 8
The answer is x = 8.</span>
Answer:
m∠C = 35°
Step-by-step explanation:
Data
From the figure, it can be seen that a right triangle is formed where CA is the hypotenuse and CD is one of the legs.
From definition:
cos(C) = adjacent/hypotenuse
cos(C) = CD/CA
cos(C) = 23/28
m∠C = arccos(23/28)
m∠C = 35°
