Step-by-step explanation:
Answer:
38
Step-by-step explanation:
Since 19 is 50% of x, we multiply it by two
19 x 2 = 38
Sum of interior angles = (n-2) × 180<span> = (5-2) x 180 = 3 x 180 = 540
so
x + 90 + 107 + 144 + 138 = 540
x + 479 = 540
x = 540 - 479
x = 61</span>
Answer:
134
Step-by-step explanation:
Using the distributive law:-
this = sqrt 14 sqrt 12 + sqrt 14 sqrt 7 - sqrt 3 sqrt 12 - sqrt 3 sqrt 7
= sqrt1 68 + sqrt 91 - sqrt 36 - sqrt 21
= sqrt 168 + sqrt 91 - sqrt21 - 6
