Find the values of x and y. The diagram is not to scale.
Aleksandr [31]

Step 1

<u>Find the value of x</u>

we know that

(x-1)\°=74\° -------> by corresponding angles, because the given lines are parallel

Solve for x

(x-1)\°=74\°\\x=74+1 \\ x=75\°

Step 2

<u>Find the value of y</u>

we know that

(x-1)+40+(y-2)=180

substitute the value of x and solve for y

(75-1)+40+(y-2)=180

74+40-2+y=180

112+y=180

y=180-112

y=68\°

therefore

<u>the answer is the option B</u>

x=75\°, y=68\°

How do I fine x in this problem. 4x+3y=12
RSB [31]

Answer:

Answer: It's relatively easy to find x in this problem. 4x+3y=12 means that the expression 3y needs to be 12 too, which gives us 12-6 or 6. That number divided by 4 is 2, so x=2! Congrats, you've found x!

Step-by-step explanation:

One way of solving this problem is to remove the parentheses all together and write the equation as 8x+6y = 54. Subtracting 54 from both sides would give us -8x + 6y = 18. The key point here is that when subtracting a negative number, we have to borrow one from our variable so instead our answer becomes (-8)x-6(y)=-54.

Susan is drawing a triangle. The first segment she draws is 6 centimeters in length, and the second segment is 8 centimeters lon
In-s [12.5K]

Answer:

B) less than 14 centimeters

Step-by-step explanation:

Given:

Length of 1 segment of triangle = 6 cm

Length of the 2 segment of the triangle = 8 cm

Angle between those 2 segments = 80°

We need to find the length of the 3 segment of the triangle.

Solution:

Now we know that;

By Triangle Inequality theorem which states that;

"The sum of the two side of the triangle must be greater than the third side of the triangle."

i.e The length of the third side should be lest than the sum of the other two sides.

Length of the third side < 8+6

Length of the third side

Hence The length of the third side should be less than 14 cm.
