We have a square here. All angles are congruent (90 degrees) so 20x would equal 90 degrees
20x=90
x=4.5
Now let’s double check
20x
20(4.5)
90
Yep the answer is choice B) x=4.5

K/13 = 0.6/0.5 what does that equal

$\frac{k}{13}$ = $\frac{0.6}{0.5}$ equals k = 15.6

First, simplify $\frac{0.6}{0.5}$ to 1.2. Your problem should look like: $\frac{k}{13}$ = 1.2
Second, multiply both sides by 13. Your problem should look like: k = 15.6, which is the answer.

What is angle A equal? <br><br> Thanks :)

Alex Ar [27]

Angle A and angle B sums up to 180 (interior angles)

6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18

angle A = 6(18)-35 = 73 degrees
