So, We Know That The Figure Shown Is A Square. So, We Need To Find The Area:
70*70 = 4900.
So, We Have:
490 - (Area Of The Triangle) = A
So, Lets Find The Area Of The Triangle.
(35*70)/2
Well, 35*70 = 2450.
So:
2450/2 = 1225.
Now, Do:
4900 - 1225 = A
4900 - 1225 = 3675
So:
3675cm² = A
Answer:
- 494
Step-by-step explanation:
Breaking down the summation into it;s component parts
= 4k -
k(k + 1) ← substitute k = 19
= (4 × 19 ) - 1.5 × (19 × 20)
= 76 - (1.5 × 380)
= 76 - 570
= 494
<h3>
Answer: 0.6</h3>
========================================
Work Shown:
sin(angle) = opposite/hypotenuse
sin(T) = VU/VT
sin(T) = 3/5
sin(T) = 0.6
0.20 so %20 because there is 20 100ths between that
