I know that i had it on a test its -2.11 Hope you ace it!
For the first one, you're answer would be AC. since C is also a right angle, and angle A is hypnotenuse to C
Answer:
1.84
Step-by-step explanation:
The given arc is a part of a unit circle centered at origin.
The x-coordinate on the unit circle represent the cosine value and y-coordinate on the unit circle represent sine value.
So, for angle equal to
°, the x coordinate represents
°.
So,
° = 0.86
Similarly, the y-coordinate of angle y represent
°.
So,
° = 0.98
Therefore, the value of
° +
° = 0.86 + 0.98 = 1.84.
Answer: 1/6
Invert 6/5 which becomes 5/6 and then multiply
3/15×5/6= 15/90
Which simplified becomes 1/6
<u>Answer</u>:
- 3
option c). is correct!
<u>Step-by-step explanation</u>:
Given :
5 ( 6 + x ) = 15
= > 30 + 5 x = 15
= > 5 x = - 30 + 15
= > 5 x = - 15
= > x = - 15 / 3
= > x = - 3
Therefore, final answer is - 3
