Find the error & explain why it is wrong:

olga nikolaevna [1]

$( { \frac{4 {x}^{3} }{ {y}^{4} }) }^{ - 2} = \frac{16x {}^{6} }{ {y}^{8} }$

$\frac{(4 {x}^{3})^{ - 2} }{ { {(y}^{4} )}^{ - 2} } = \frac{16 {x}^{6} }{ {y}^{8} }$

$\frac{ {16x}^{ - 6} }{ {y }^{ - 8} } = \frac{ {16x}^{6} }{ {y}^{8} }$

The power of -2 was mistook as 2.

Find the measure of each angle listed below. Enter only numbers without space.

Sloan [31]

Answer:

∠PTQ = 45°
∠QTR = 15°
∠PTS = 120°

Step-by-step explanation:

Parallelogram PTSR is divided into two equilateral triangles by diagonal RT. All of the acute angles in that quadrilateral are 60°, and the obtuse angles are 120° (2×60° and also the supplement of 60°).

Triangle PTQ is an isosceles right triangle, so its acute angles are 45°.

∠PTQ = 45°

∠QTR = ∠PTR -∠PTQ = 60° -45°

∠QTR = 15°

∠PTS = 120° . . . . . . obtuse angle in PTSR; sum of ∠PTR and ∠RTS
