Answer:
54° and 110°
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral are supplementary, sum to 180°
(9)
19x - 26 + 7x - 2 = 180
26x - 28 = 180 ( add 28 to both sides )
26x = 208 ( divide both sides by 26 )
x = 8
Then
∠ EFG = 7x - 2 = 7(8) - 2 = 56 - 2 = 54°
(10)
21x - 33 + 14x + 3 = 180
35x - 30 = 180 ( add 30 to both sides )
35x = 210 ( divide both sides by 35 )
x = 6
Then
∠ YVW = 14x + 3 = 14(6) + 3 = 84 + 3 = 87°
The inscribed angle YVW is half the measure of its intercepted arc YW, so
arc YW = 2 × 87° = 174°, then
arc XW = 174° - 64° = 110°
Answer:
x = 1/2y + 1
y = 2x - 2
Step-by-step explanation:
Let's solve for x.
4x−2y=4
Step 1: Add 2y to both sides.
4x−2y+2y=4+2y
4x=2y+4
Step 2: Divide both sides by 4.
4x
4
=
2y+4
4
x=

2
y+1
Answer:
x=
1
2
y+1
Let's solve for y.
4x−2y=4
Step 1: Add -4x to both sides.
4x−2y+−4x=4+−4x
−2y=−4x+4
Step 2: Divide both sides by -2.
−2y
−2
=
−4x+4
−2
y=2x−2
Answer:
y=2x−2

brainliest?
If you have a graphing calculator, you could use it to solve this question.
If you have a TI-84, go to <em>MATH</em> then <em>PROB</em> then <em>3: nPr</em>
From there, all you have to do is type in 7 and 3 in their correct spots to get 210 as your answer.
3/7 for sure hope this helps
Answer:
Not possible
It doesn't factorise because we can't pull out any highest common multiple.
Also, to be able to factorise a quadratic, it must be in the general form of ax^2 + bx + c.
Hope this helps!
