Answer:
cos(55) = 11/x
Step-by-step explanation:
We have the hypotenuse (x) and an angle adjacent to 55 (11). The only trigonometric formula that uses adjacent and hypotenuse is cosine (adjacent/hypotenuse), so that will be your answer.
(29-22)*26+(26-21)*22
Cut the figure into 2 then find the unknown lengths to find each part. Add them together, and you'll get the answer.
To write an equation you need a slop and y intercept. To find the slop use the formula y2-y1 /x2-x1. and for the y intercept use the formula y=mx+b
The equidistant point for all three, will be the "centroid" of their triangular locations
thus
The value of root 10 is between 3 and 3.5
