There are two sides (heads and tails). So one head would be 1/2, and one tail would also be 1/2.
Answer: x = 16°
Step-by-step explanation:
- This is a right triangle, which means all angles add up to 180°.
- One of the angle is already determined to be 90°, that means the sum of the other two angles must also be 90° in order to meet a total of 180°.
This means (x+26)° + 3x° = 90°.
Solve for x:
x + 26 + 3x = 90
x + 3x = 90 - 26
4x = 64
x = 64 ÷ 4 = 16°
Check the picture below.
make sure your calculator is in Degree mode.
Answer:
55 ° is correct answer option (c)
2x-9= (-7^2)
2x-9=49
2×=49+9
2x=58
x=58/2
x=29
