Answer:
F(2)?
Step-by-step explanation:
Answer:
m∠BCD = 120°
Step-by-step explanation:
Since the interior angles of a quadrilateral add up to 360°, then we get:
2x+x+2x+x=360°
6x=360°
<em>Divide both sides by 6</em>
x=60°
Since ∠BCD's value is 2x and x is equal to 60°, then ∠BCD is 120°.
We know that the diagonals of a square bisect each other which results in the formation of 4 - 90° angles . Which means ZX = 2 × WT . Then ,
= ZX = 2 × 6
= ZX = 12 ( ZX is a diagonal )
Side XY =
XY = √2 d/2
XY = √2 . 12/2
XY = 8.48528
m∠WTZ = 90° ( as the diagonals of a square intersect to form a complete angle ( 360° ) which is divided into four equal parts , each part being 90° )
m∠WTZ = 90°
m∠WYX = 45° ( WYX is half of one of the interior angles in this square which will mean it will be equal to 45° )
Therefore , m∠WYX = 45°
<h2>In short : </h2>
ZX = 12
XY = 8.48528
m∠WTZ = 90°
m∠WYX = 45°
Answer:
Step-by-step explanation:
2(2x-1)=6(x+2) PEDMAS
4x-2=6x+12 subtract 4x from both sides
-2=2x+12 subtract 12
-14=2x divide by 2
x= -7
Answer:
x = 20
Step-by-step explanation:
Using the vertical angle theorem, you will find that 7x - 99 = 2x + 1.
7x - 99 = 2x + 1
+99 both sides
7x = 2x + 100
-2x both sides
5x = 100
÷5 both sides
x = 20
The answer is x = 20.
