Answer:
x = 17.6
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj / hyp
cos 51 = x /28
28 cos 51= x
x=17.62097
To the nearest tenth
x = 17.6
Algebra 1 is a basic algebra course usually taken in freshman year (9th grade). Common Core guidelines dominate the curriculum. It is faster paced than middle school math courses. Algebra 2 is a more advanced algebra course usually taken in junior year (11th grade). Algebra 2 is paced even faster and builds on what you learn in A1 and geometry. Both deal with variables and the manipulation of numbers.
