Answer:
3. (3,-4)
Step-by-step explanation:
The diagonals of a rectangle are congruent so set them equal to each other to get x = 2x - 7. isolate the variable (0 = x - 7 — x = 7) to get x = 7. the diagonals are seven.
Answer:
Step-by-step explanation:
Angle 4 = angle 1 and angle 3 =angle 2 Corresponding angles for two parallel lines BD and AE
Triangle AED ||| BDE Angle angle congruent
... By compendo and dividendo
Thus proved
Since two lines are parallel we have corresponding angles equal and also
sides will be proportional in similar triangles
Using that and adjusting compendo and dividendo we get the desired result
Answer:
x = 4
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the remote interior angles.
18x +5 = (46) +(-1 +8x)
10x = 40 . . . . . . . . . . . . . subtract (5+8x) from both sides, simplify
x = 4 . . . . . . divide by 10

<em>Additional comment</em>
The exterior angle is (18)(4) +5 = 77°. The marked unknown interior angle is -1+(8)(4) = 31°. The sum of the two remote interior angles is 46°+31° = 77°. The unmarked interior angle is 180°-77° = 103°.
