Yes that is the answer 19
We know that ON = 80 cm and ∠ O = 37°.
cos 37° = 4/5
Adjacent / Hypotenuse = cos∠O
80/OP = cos 37°
80/ OP = 4/5
OP = 80 : 4/5 = 80 · 5/4 = 100
Answer:
d. 100 cm.
I think you substitute 189 for the letter t.
You actually do substitute.
2 + 13x, because (19x − 6x) + 2 = 13x + 2 = 2 + 13x
