SA=(a+b+c) h+bh
=(5+12+13)*4+5*12
=20*4+60
=80+60
=140 cm squared
I am assuming that you will need to do Pythagorus Theorem to find the 3rd side length. If thats the case then you will need to do the following formula : a^2 + b^2 = <span>√(c)
So 15^2 + 30^2 = </span>√(c)
= 33.5 inches
The third angle would be 115 because 180 - 45 - 20 = 115
I hope this helped.
Explanation:
From the diagram, one square box represensts 1 units. The pre image of parallelogram ABCD is A'B'C'D' as shown. We can see that the parallelogram ABCD at the right shifted towards the left by 3 units (note the 1 unit represents one squaren
Hence we can conclude that the parallelogram ABCD shifts 3 units to the left to produce a pre-image A'B'C'D'ote the 1 unit represents one square)
Hence we can conclude that the para
If u look up the answers to those questions they will be on a different site not this one tho if u need help lmk
