Question

xsinsquare45+cossquare60+tansqure45=3/4

Answer 1

Answer:

x = -1

Step-by-step explanation:

$xsin^{2} 45+cos^{2} 60+tan^{2} 45=3/4\\x* (1/\sqrt{2} )^{2} + (1/2)^{2} + 1^{2} = 3/4 \\1/2*x + 1/4 + 1 = 3/4\\1/2*x + 5/4 = 3/4\\1/2*x = 3/4 - 5/4\\1/2*x = -2/4\\1/2*x = -1/2\\\x = -1/2 * 2/1\\x= -1$
