Answer:

hi there!

the correct answer is: 29 degrees

Step-by-step explanation:

if you refer to the picture I have drawn below angle b is supplementary to the the 119 angle (i know I accidentally wrote 118) that means in order to find angle b you need to do 180-119 which equals 61

then since all angles in a triangle add up to 180, you need to perform (180-90-61) which equals 29

Step-by-step explanation:

m<DAC is the exterior angle of the right angle triangle, where m<ACB and m<ABC are the interior angles of the triangle opposite to the exterior angle

Sum of the opposite interior angles is equal to the exterior angle

m<ACB+ m<ABC=m<DAC

a°+90°= 119°

a°=119-90°

a°=29°

Consider the explicit formulas for two sequence ​
BaLLatris [955]

These are the formulas right?.. I hope so, anyways..

- f(n)= 2^(n-1) -1

- g(n)=3n+6  

f(7)=2^{7-1}-1  -  f(7)=2^{6}-1  -  f(7)=64-1  -  f<u>(7) = 63 </u>

g(10)=3\X 10+6  -  g(10)=30+6  -  g<u>(10) = 36</u>

= <u>f(7)>g(10)</u>

I hope that it helped..
