Answer:

5/12

Step-by-step explanation:

We have to find same denominator for both fractions;

3/4= 9/12

1/3= 4/12

9/12 minus 4/12= 5/12

You will need 5/12 powder more for the experiment.

Answer:

Option A 90,68

$m\angle 1=90^o$

$m\angle 2=68^o$

Step-by-step explanation:

see the attached figure to better understand the problem

The figure shows a kite

we know that

A kite properties include

1) two pairs of consecutive, congruent sides

2) congruent non-vertex angles

3) perpendicular diagonals

Find the measure of angle 1

we have that

$m\angle 1=90^o$ ----> by the diagonals are perpendicular

Find the measure of angle 2

we know that

triangle AEB is congruent with triangle CEB

$m\angle EAB=m\angle ECB=m\angle 2$

In the right triangle EAB

$m\angle EAB+22^o=90^o$ ----> by complementary angles in a right triangle

$m\angle EAB=90^o-22^o=68^o$

therefore

$m\angle 2=68^o$
