Answer:
35
Step-by-step explanation:
Since the two sides are equal in a parallelogram angle B = y ,so we have angle to be equal to 145°
We sum both angles and divide from
360° - [145° +145°]
360° - 290° = 70
Since the left sides( X And Z) are equal then we divide what we got into 2
70 ÷ 2 = 35
therefore angle X equals 35

Answer:
x = -62/7
Step-by-step explanation:
-7x+(-21)=41
-7x -21 =41
Add 21 to each side
-7x-21+21 = 41+21
-7x = 62
Divide by -7
-7x/-7 = 62/-7
x =- 62/7
Answer:
-15
Step-by-step explanation:
-24 + (1-4)^2 (solve parentheses first)
= -24 + (-3)^2 (solve exponent)
= -24 + 9
= -15
Hello!
We are told that n and m are parallel.
The angle that measures 105 degrees is supplementary with the alternate interior angle of the angle which measures (3x - 18) degrees. Supplementary angles add to equal 180 degrees, so we can make an equation by first finding the measure of the alternate interior angle.
180 - 105 = 75
The alternate interior angle measures 75 degrees, so we can set that equal to 3x - 18 to solve for x since alternate interior angles are congruent.
75 = 3x - 18
93 = 3x
31 = x
Answer:
x = 31
