Lynna [10]

Answer:

$\left \{ {{\theta_1=\frac{\pi }{4} } \atop {\theta_2=\frac{3\pi }{4} }} \right. .$

Step-by-step explanation:

$2*cos^2\theta-1=0\ \ \ \ (0^0\leq \theta\leq 360^0)\ \ \ \ \ \theta=?\\2*cos^2\theta-(sin^2\theta+cos^2\theta)=0\\2*cos^2\theta-sin^2\theta-cos^2\theta=0\\cos^2\theta-sin^2\theta=0\\cos2\theta=0\\0^0\leq \theta\leq 360^0\ \ \ \ \Rightarrow\\\left \{ {{2\theta=\frac{\pi }{2}\ |:2 } \atop {2\theta=\frac{3\pi }{2}\ |:2 }} \right. \ \ \ \ \left \{ {{\theta_1=\frac{\pi }{4} } \atop {\theta_2=\frac{3\pi }{4} }} \right. .$

Plz help I dont understand

postnew [5]

Answer:

50=2(10+w)

Step-by-step explanation:

We know that perimeter is equal to the sides of a shape

A rectangle has two of the same length and two of the same width

P=2l+2w

We know the perimeter and length so plug that in and solve for w

50=2(10)+2w

50=2(10+w) - That matches answer choice D

30=2w

w=15
