5 0

Answer:

x = 10°

Step-by-step explanation:

The diagonals of a rhombus divide the figure into congruent right triangles. That means the two marked acute angles are complementary.

<h3>solve for x</h3>

Complementary angles total 90°, so the relation we can use to find x is ...

(3x -13) +(8x -7) = 90

11x = 110 . . . . . . . . . add 20

x = 10 . . . . . . . . . divide by the coefficient of x

The value of x is 10°.

Question 5

sergey [27]

Explanation : If 66 is a factor of this unknown value, then 22 must be as well considering that 22 is a factor off 66. Let's say that this large value is 330. It is a multiple of 66, as 66 $*$ 5 = 330. At the same time 22 $*$ 15 = 330, so 330 is a multiple of 22 as well - or vice versa, 12 is a factor of 330.

We can also tell that 15, 22 fit into 330 through another approach. 22 $*$ 3 = 66, and 66 $*$ 5 = 330, so 5 $*$ 3 = 15 - the same value. This proves that 22 will always be a factor of a value that is the factor of 66.

Dmitry_Shevchenko [17]

Answer:

None of the above answers

Step-by-step explanation:

Form a table as shown

Months Teddy Bears Rabbits Cats Horses Others Totals toys

September 225 275 245 260 199 1204

October 346 308 186 297 285 1422

Trends

Cats decreased from 245 to 186

Others increased from 199 to 285,

285-199 = 86

percent increase was = increase/original quantity *100

86/199 *100 =43.22%

Total number of stuffed toys increased from 1204 to 1422

percent increase = (1422-1204)/1204 *100 = 218/1204 *100 =18.11%
