Answer:
A = 73.33
B = 53.33
C = 53.33
Step-by-step explanation:
Since they are in a triangle, the sum of the three angles = 180
A + B + C = 180 ••••••(i)
Since B and C are congruent, it means that they are equal;
hence B = C ••••••(ii)
We can rewrite equation i as;
A + B + B = 180
A + 2B = 180 ••••••(iii)
Lastly;
B = A -20 •••••(iv)
Substitute iv into iii
A + 2(A -20) = 180
A + 2A -40 = 180
3A = 180 + 40
3A = 220
A = 220/3 = 73.33
But B = C = A -20 = 73.33 -20 = 53.33
None of the answer matches the correct ans
(3.4×10-14)(1.8×10^28)
20(1.8×10^28)
3.6×10^29

Answer:
<em><u>Letter C </u></em>
<u>correct!</u>
Step-by-step explanation:
20 + 15 = 35
22 + 13 = 35
25 + 10 = 35
so the answer is 35
<u>correct!</u>
Answer: 30
Step-by-step explanation:
Since this is a right triangle, the pythagorean theorem says
![x^2 + 16^2 = 34^2](https://tex.z-dn.net/?f=x%5E2%20%2B%2016%5E2%20%3D%2034%5E2)
So if you rearrange for
you get
