Answer 1

(1) (¾)^-2 × (4/3)^-2

= (4/3)² × (¾)²

= 16/9 × 9/16

= 1

(2) Adjacent angles :–

Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way .

Example – Two pizza slices next to each other in the pizza box form a pair of adjacent angles when we trace their sides.

Answer 2

Answer:

1.

$( \frac{3}{4} )^{ - 2} \times ( \frac{4}{3} ) ^{ - 2}$

$= ( \frac{3}{4} ) ^{ - 2} \times( { \frac{3}{4} })^{2}$

We Changed the sign of the exponent by rewriting the base as its reciprocal.

$= ( \frac{3}{4} ) ^{ - 2 + 2}$

$= ( \frac{3}{4} ) ^{0}$

$= 1 \: is \: answer$

2.

Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way.

example. two pizza slices next to each other in the pizza box form a pair of adjacent angles when we trace their sides.

3.

$[ ( - 9) \times 8 ] \times ( - 5)$

$= [ - 9 \times 8] \times ( - 5)$

$= [ - 72 ] \times ( - 5)$

$= 360$

4.

Sum of two complementary angles is 90° and sum of two supplementary angles is 180°.

supplementary angle of 90° is 180°−90°=90°

supplement of 90° is 0° angle

The complement of a 90° angle is a 0° angle.
