Kevin drew a triangle with angle measures of 30 degrees and 40 degrees and side measures of 5cm,7cm, and 8cm. Explain, using sides and angles, which type of triangle Kevin drew?

Given: f(x) = 2x + 5 and g(x) = x2 and h(x) = -2x h(g(f( = x2+ vx+ x + y

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
