An acute angle is less than 90 degrees
3=6 ; 6+8=180
(2x-5)+(x+5)=180
X=60
6=115, 8=65
Hope that answer can help you!
Answer:
19Sin A - (10/sin A)
Step-by-step explanation:
We want to simplify;
9Sin A + 3cosec A + 10sin A - 13Cosec A
Let's rearrange it for ease of addition;
(9Sin A + 10sin A) + (3cosec A - 13Cosec A)
>> 19Sin A - 10cosec A
Now, from trigonometric ratios, we know that; Cosec A = 1/Sin A
Thus; 10cosec A = 10/sin A
Thus, we now have;
19Sin A - (10/sin A)
Let's get started!! hahah
The tenths place is the place right after the decimal
When rounding,
This number either stays the same (if the number after it is lower than 5)
or increases by 1 (if the number after it is 5 or greater)
1) 29.516. 5 is in the tenths place look at the number after this.. 1: it is LESS THAN 5 so the answer is 29.5
2) 84.78 7 is in the tenths place look at the number after this.. 8: it is GREATER THAN 5 so the answer is 84.8
3)1017.36 3 is the tenths place look at the number after this.. 6: it is GREATER THAN 5 so the answer is 1017.4
Hope that helps
