Answer:

x = 20°

y = 70°

Step-by-step explanation:

the angle adjacent to the 40° angle must be 140° because the two angles form a straight line (which contains 180°)

in the isosceles triangle with the 'x', that means the other two angles must be equal and are (180-140) ÷ 2, which equals 20°

to find 'y', consider the larger right triangle with angles of 90° and 20°; angle y must equal 180 - (90 + 20) = 70°

The sum of the digits of a two-digit number is 8. The difference between the number and the reversed number is 10 more than the

Vesna [10]

Answer:

The number is 62

Step-by-step explanation:

Let the digits of the number be T and U;

A 2 digit number is represented as: 10T + U

So,

$T + U = 8$

$10T + U - (10U + T) = 10 + 10U + T$

Required

Find the digit

Make U the subject in the first equation

$U = 8 - T$

Substitute 8 - T for U in the second

$10T + U - (10U + T) = 10 + 10U + T$

$10T + 8 - T - (10*(8-T) + T) = 10 + 10(8 - T) + T$

$10T + 8 - T - (80-10T + T) = 10 + 80 - 10T+ T$

$10T + 8 - T -80+10T - T = 10 + 80 - 10T+ T$

Collect Like Terms

$10T + 10T - T- T + 8 -80 = 10 + 80 - 10T+ T$

$18T -72 = 90 - 9T$

$9T + 18T = 90 + 72$

$27T = 162$

$T = 162/27$

$T = 6$

Recall that:

$U = 8 - T$

$U = 8 - 6$

$U = 2$

<em>Hence, the number is 62</em>
