Answer:

56

Step-by-step explanation:

Missing length = x + 21

Based on the Three Parallel Lines Theorem, we have:

x/21 = 20/12

Cross multiply

x*12 = 20*21

12x = 420

12x/12 = 420/12

x = 35

✅Missing length = x + 21

Plug in the value of x

= 35 + 21

= 56

Burka [1]

Answer:

10

Step-by-step explanation:

<em>m∠</em>2 and <em>m∠</em>1 are congruent by the Corresponding Angles Theorem; we set both expressions equal to each other:

[80 - x]° = [90 - 2x]°

+ x° + x°

______________

80° = [90 - x]°

-90° - 90°

__________

−10° = [−x]°

10° = x

A jacket costs $90 at full price. It is on sale for 30% off the regular price. What is the amount of the discount?
Sav [38]
Remember that when you find 30% of the number you have to subtract the 30% from your original $90 because it is 30% off the original price.
