Rhombus has opposite angles equal therefore, 3x=45 and 4y+21=7y
3x=45
x=45/3
x=15

4y+21=7y
4y-7y= -21 multiply by -1
3y=21
y=21/3
y=7

Nitella [24]

Answer:

Th number of pages is 33

Step-by-step explanation:

The ratio of the number of pages of text shown in the illustration is 3:2. This implies that for every 2 pages of illustrations, there are 3 pages of text. Therefore, for 22 pages of illustration we shall have;

2 page of illustration = 3 page of text

Then

22 page of illustration = x pages of text

Then by Cross multiplication

$22 \times 3 = x \times 2$

$66 = 2x$

x = $\frac{66}{2}$

x = 33
