Answer:
90
Step-by-step explanation:
Be sure to use PEMDAS. Begin with parentheses, the move to multiplication, then adding.
20 + 3(7 + 4) + 5 + 2(7+9)
20 + 3(11) + 5 + 2(16)
20 + 33 + 5 + 32
You can add those final four numbers in any order you want, to get a sum of 90.

Answer:
40
Step-by-step explanation:
26/sin(40 degrees) = 40.4488
All the angles of a triangle add up to 180 degrees.
30+39+<4= 180
69+<4= 180
Subtract 69 on both sides.
<4= 111 degrees
<1 and <4 are supplementary and adjacent. They equal 180 degrees as well.
111+<1= 180
<1= 69 degrees
I hope this helps!
