bbwebbcubbuce good hbu? and stop ur not.
Because is the ratio of two natural numbers
8.8=88/10=44/5
i'm 85% certain the answer is C. Fiona is not correct because the coin will definitely land in the white area .
10. 4 + 5x < 54
- subtract 4 to the right
- divide both sides by 5
answer: x < 10
11. 2(x + 4) + 3 = 6 - x
- distribute 2 to x and 4
- add 8 and 3
- add -x to left side
- subtract 11 to right side
- divide both sides by 3
answer: x = -5/3
Quite easy!
Just follow SOH-CAH-TOA
Sine Opposite Hypotenuse; Cosine Adjacent Hypotenuse; Tangent Opposite Adjacent.
To find the measure of angle x, use tangent or opposite over adjacent.
So 26/53= 0.49
And using a tangent table, the closest to 0.49 is 26°
