Hello!
The area of a triangle is always 180°
And we know that angle "A" is 90°
So we can do 180 - 90 = 90
Which means that.
(2x+14) + (4x-26) = 90
You combine like terms
6x - 12 = 90
add 12 to each side.
6x = 102
divide by 6 on both sides
x = 17
So the answer is 17°
Hope this helps!
Answer:
1:2
Step-by-step explanation:
The total number of marbles is
3+5+8 = 16
blue : total
8 : 16
Divide each side by 8
8/8 : 16/8
1:2
Answer:
(x-2)^2 +(y+5)^2=4^2
Step-by-step explanation:
x minus 2 squared + y plus 5 squared = radius squared
Answer:
Step-by-step explanation:
Let's solve x^2 - 2x + 2 = 0 using "completing the square:"
1. Take the coefficient of x: It is -2.
2. Halve this, obtaining -1.
3. Square this result, obtaining 1.
4. Add 1, and then subtract 1, between -2x + 2:
x^2 - 2x + 1 - 1 + 2 = 0
5. Rewrite x^2 - 2x + 1 + 1 = 0 beginning with the square of a binomial
(x - 1)^2 + 1 = 0, or (x - 1)^2 = -1
6. Take the square root of both sides, obtaining x - 1 = ±i, or x = 1 ±i
7. Write out the roots: they are x = 1 + i and x = 1 - i (two complex, different roots). No real roots, so the last command of this question is irrelevant. The graph never touches the x-axis; the graph is in Quadrants I and II and is that of a parabola that opens up.
The dividend will have to be positive, while the divisor will be negative. By the way, nice profile pick. Nightcore all the way.
