Answer:
55
Step-by-step explanation:
Since this is an isosceles triangle, the angles at the bases of the identical legs must be equal
<A = <C
3x+40 =x+50
Subtract x from each side
3x-x+40 = x+50-x
2x +40 = 50
Subtract 40 from each side
2x+40-40=50-40
2x = 10
Divide each side by 2
2x/2=10/2
x = 5
We want to find <A
3x+40
3(5)+40
15+40
55
X/y (3/-1 just look at where the a is if it is o. ln the x axis or y axis then look to see if it's positive or negative
Answer:
-4/3
Step-by-step explanation:
Using the order of operations you can simply go from left to right with it.
5x2 + 3y2 = 2
10 + 3y2 = 2 Here I just multiplied 5x2
Now we can continue with the equation, keeping in mind you go left to right.
10 + 3y2 = 2
10+ 6y = 2 3y times 2 is 6y.
So we have to continue by balancing the equation, what you do to one side you do to the other.
10 + 6y = 2
<u>-10 -10</u>
6y = -8
6y/6 is y and -8/6 can be reduced to -4/3 so that is the answer!
Hope that helps and have a great day!
Answer:
3
Step-by-step explanation:
Gradient is also called slope .
=> m = y₂ - y₁ / x₂ - x₁
=> m = 5a + a / 6a - 4a
=> m = 6a / 2a
=> m = 3
