Answer:

10) 3

11) no

12) kayla's statement is incorrect because the diagonals of a rectangle do not intersect each other at 90 degree like a rhombus.

13) Andy’s statement is incorrect because

Quadrilaterals have 4 sides and 4angles. The exterior angles of any convex polygon add up to 360 degrees ( 4 right angles). If an interior angle is a right angle then the corresponding exterior angle must also be a right angle

Give triangle TRY, find TY. Round your answer to the nearest hundredth.

3241004551 [841]

The length of TY is 2.26.

Solution:

In ΔTRY, θ = 37°, Adjacent side = 3.

To find the length of TY.

Using trigonometry identity,

$$\tan\theta=\frac{{opposite}}{{Adjacent}}$

$$\tan37^\circ=\frac{{TY}}{3}$

$$3\tan37^\circ=TY$

$$3\times 0.75355=TY$

$$TY=2.26065$

TY = 2.26

Hence the length of TY is 2.26.
